1 instrucalc features more than 70 routines associated with control valves, ISO flow elements, relief valves and rupture disks, and calculates process data at flow conditions for a comprehensive range of fluids in either single components or mixtures. instrucalc calculates the sizes of control valves, flow elements and relief devices; produces data sheets for calculated items, and prepares instrument summaries and uses data sheets as a database for generating reports. INSTRUCALC FEATURES The Control Valve sizing program to "ANSI/ISA The Relief Valve sizing program to "API RP " which includes 2 phase flow sizing. Tank venting to "API Std 2000" 5th Edition April 1998." The Flow Element sizing program combines all flow calculations into one program and provides a means for transferring data between the calculations for optimum selection. Separate tables for calculation data, units' data, data sheets, pressure drop calculations, chemical properties composition data and water hammer data. This allows for data to be available for manipulation. Technique for showing cavitation in restriction orifices and venturi meters (Flow Elements) Expanded vortex meter sizes up to size 36 (Flow Elements) Incorporation of Z-factor in gas-flow for sizing Flow Elements AGA8 option for Natural Gas in Flow Elements PRV Program provides an option to calculate flow rate for a known size RV. Status shows clearly flashing, cavitation and choking of control valves. Outlet of control valves - flow velocity at outlet flange Allows for Density input instead of Specific Gravity in all Programs Allows absolute and gauge units for all pressure inputs Operational Settings: Program runs in Windows 7 64 bit or 32 bit. Licence metering protects the network version. Excel Import/Export for process data Database Print manager with options to print the entire database stored data and all the calculations or any combination of them.\ Data files are Microsoft Access.

2 CONTROL VALVE SIZING MODULE Three programs are available, each for standard and low flow valves: Liquid Flow Gas Flow Two Phase Flow Options for each valve calculation are: Calculate Valve Size Calculate Flow Rate Calculate Valve Pressure Drop Three cases are provided for each calculation: Maximum flow Normal flow Minimum flow Aids for the calculations are - Typical valve data tables Fluid properties at flowing conditions A program to calculate the valve pressure drop available in the piping system Calculation options and units are set according the image opposite. After using the above for normal flow to determine the valve size, scroll bars will change the flow, recalculate the data and determine the maximum and minimum flows that the piping system will allow. The programs have a data base of typical valves so that different valve data can be entered into the calculation in order to make the best selection. Try several and calculate until a valve style and size is selected which has the rangeability and does not have cavitation or noise problems. When a final selection is made the exact manufacturers data can be entered for a final calculation. Finally, for liquid valves in long piping systems, take the option for the minimum closing time, this is the water hammer program to determine if a special closing time is required to avoid water hammer. 2

3 Control Valve Sizing Philosophy Each manufacturer has its own formula for determining the valve size, the valve noise and the cavitation characteristics. This program uses the ISA sizing formulas, it uses the Masoneilan noise prediction method and incipient cavitation technique. The object of the program is to determine the valve size, the cavitation, flashing and noise problems and prepare a data sheet suitable for bid purposes. Some manufacturers may differ from these conclusions, usually the variations are minor and do not change the size and style. Occasionally the noise and cavitation characteristics will differ so that engineering judgment may be called for. The failure of a valve because of cavitation erosion can be extremely expensive. Sometimes a change in body style, or hardened trim is sufficient to eliminate the problem. The typical valve data files are in ASCII format, three options are provided. They are Standard Valves, Low Flow Valves and a file for User Valves. They can be modified from within the program. The Standard file is based on Masoneilan data. The Low Flow file is based on Research Control Valves data. If another manufacturer is preferred edit the User valve file as required. If the manufacturer does not use the incipient cavitation factor (Kc) then leave the box empty. ISA S75 shows data for a typical file. Control Valve Graphical Display Graphs for Control Valves and Flow Elements calculations can be generated. Graphs available for Control Valves are: valve Cv and flow; valve pressure drop and flow; linear trim; and, equal percent trim. Flow Element graphs include: flow and differential.

4 FLOW ELEMENTS MODULE Orifice and Restrictor Calculations: instrucalc calculates the orifice size, flowrate or differential range, which enables the user to select the flowrate with optimum accuracy. It provides the recommended size and corrects the orifice size accordingly. Process data can be converted individually or jointly with a simple "click of the mouse." ISO orifice plate calculations have been updated to ISO 5167, The material yield strengths file calculates orifice plate thickness automatically. The thickness is calculated for each orifice based on the pressure and temperature of the selected plate material. Also ISO Venture, ASME Long Radius Nozzle and concentric orifice plate (thick and thin) for gas and liquid services using Miller's Handbook, 3rd edition, Available flow elements are shown in the image below. Calculations: Calculate either.-- Orifice size, Flow rate or Differential range Calculate vent or drain hole size if required Calculate the minimum plate thickness Calculate permanent pressure and power loss Calculate accuracy percentage Supply fluid properties at flow conditions Supply steam data Supply pipe sizes Provide material selection Use English or SI engineering units in any mixture Use mass or volume flow units Import process data Print a calculation sheet using the Windows Print Manager 4

5 Calculation options are set according the image opposite. Prepare instrument data sheets WUSIWUG style Initially general- sheets for bid purposes Supply data base of standard specification items After vendor selection, revise for permanent records Print a data sheet using the Windows Print Manager Print a list of saved records Print all records Print selected records Print only records having required characteristics 5

6 RELIEF DEVICE SIZING MODULE Calculation Dialog Data Sheet The user should be familiar with the ASME Section 8 and relevant API publications: The Liquid Relief - known flow calculation has options to size for single or multiple valves or non-certified valves. The Gas Relief - known flow calculation has options for section 1, section 8 or the fire code. The reaction force and the noise level are calculated The Steam Relief - known flow calculation has options for Section 1, section 8 and the fire code and calculates the reaction force and noise level The Two phase - known flow calculation has options for Section 1, section 8 and the fire code and calculates the reaction force and noise level, It has 7 different two phase calculations. The Heat Exchanger - entrapped liquid calculation is for a blocked in liquid filled exchanger which has the heat turned on. It calculates the flow caused by the liquid expansion The Heat Exchanger - Tube failure calculation is for tube rupture where the tube pressure is 50% greater than the shell pressure. It assumes no vaporization of the shell side product. The Pipeline - Entrapped liquid calculation is for liquid expansion in long, blocked in, pipelines on a hot day. It usually only takes a very small relief valve to avoid blowing the gaskets The Fire size - Liquid vaporization is the most complex calculation. It gathers the flame wetted area of up to 15 liquid containing vessels. The heat input is calculated either by The API 520 or the National Fire Protection Association NFPA #30, method and a relieving flow rate is determined. The reaction force and relieving noise level are also calculated. The Fire size - Gas expansion also gathers the flame wetted area, this time of up to 15 gas containing vessels. The maximum flow is then back calculated from the valve size. The reaction force and relieving noise level are then calculated. 6

9 NETWORK LICENCE instrucalc network version was developed to monitor the number of simultaneous users. A license file is installed on the server drive that controls and regulates the number of simultaneous users equal to that of the purchased license. The client workstations look at the license on the server to see if there are open licenses before launching the program. After install procedure on the network server, each workstation (that s licensed) must have the full program loaded onto it in order for the program to run. The client machine installed software must then have the paths to the data files set to wherever the user s database files will be stored. SUPPLY AND ACTIVATION Permanent licenses of instrucalc are supplied only after receipt of payment in full. We supply instrucalc only via a digital download software and manual. After initial installation (or at the end of the evaluation period) you will need to register the software for a permanent licence activation code. The activation code is issued by the developer, not Accutech. The developer is on Central US Time Zone and you need to keep this in mind when contacting the developer.
