Sažetak
Flow Engineering - BS1042 (FE-BS) Version 2.0 is a software package aimed primarily to flow measurement engineers. It could be also helpful to those who deal with the physical-property data. The FE-BS is powerful, yet easy to use tool which transforms the engineering of the differential devices into an easy task. It solves the following engineering problems: - flow-rate calculation - differential pressure calculation - bore sizing The FE-BS is based primarily on the British Standard BS-1042, Section 1.2. FE-BS covers 14 different measurement conditions specified by BS-1042, Section 1.2: - Orifice: Flange tappings (drain hole) - Orifice: Corner tappings (drain hole) - Orifice: D and D/2 tappings (drain hole) - ISA 1932 nozzle (drain hole) - Orifice: Corner tappings (Pipe diameter: 25mm-50mm) - Orifice: Corner tappings (no upstream pipeline) - ISA 1932 nozzle (no upstream pipeline) - Venturi nozzle (no upstream pipeline) - Orifice: Corner tappings (no downstream pipeline) - ISA 1932 nozzle (no downstream pipeline) - Venturi nozzle (no downstream pipeline) - Orifice: Conical entrance (Pipe diameter: 25mm-50mm) - Orifice: Quarter circle (Pipe diameter: 25mm-50mm) - Orifice: Eccentric (Pipe diameter: (25mm-50mm) FE-BS covers the following fluids: - Natural Gas (AGA-8) - Water/Steam - Arbitrary Fluid The computation of fluid properties for a natural gas and water/steam is fully automated. The calculation of density and compressibility of the natural gas mixture is in accordance with AGA-8: Compressibility and Supercompressibility for Natural Gas and Other Hydrocarbon Gases. The computation of natural gas properties such as viscosity, isentropic exponent, pseudo-reduced and pseudo-critical properties, gas-mixture relative molecular mass, etc., are in accordance with the procedures elaborated in the book of Miller: Flow Engineering Handbook, McGraw-Hill, New York, 1989. The calculation of the superior- and inferior-calorific values for the natural gas are in accordance with ISO 6976. The calculation of properties of water and steam are in accordance with The 1967 IFC Formulation for Industrial Use. The FE-BS also implements the engineering equations, in accordance with BS-1042, for arbitrary fluids. In these cases it is necessary to enter certain fluid properties into the project as the input parameters. These parameters are fluid density, fluid viscosity and isentropic exponent at the flowing conditions. The FE-BS enables the following input/output operations: - Save/Load project - Print project - Print project to file - Print project ASCII to file The FE-BS extensively reports the corresponding errors and warnings if input and/or output data are out of limits and recommendations imposed by standards and helps you locate and correct the errors. To learn more about FE-BS you can run FE-BS Help file from the MS Windows File Manager. You can also select Contents from the FE-BS Help menu to invoke Help file or press F1 key for the corresponding context sensitive help. FE-BS package includes: - User's Guide - Installation disks (3.5") - Hardware protection key
