Here are the ultimate, user-friendly, software programs in liquid and gas pipeline and pump performance. Quick and accurate solution to engineering problems involving pumps, compressors and pipelines in a user-friendly Windows environment.
 
LIQTHERM simulates the steady state hydraulics of a buried, heated liquid pipeline with several pump and heater stations. Pipe may be insulated or bare, above or below ground. Dynamic batching, injections, delivery, DRA and pump curve data may be used. Pipe branches and loops may be modeled. Variable speed pumps and cost calculations. Version 6.0 - Graphically build pipeline model
 

 
GASMOD is a hydraulic simulation software for gas pipelines considering heat transfer between the pipe and surroundings. Gas compositions may be specified. Multiple compressor stations along the pipeline may be specified. Pressure drop calculations may be based on AGA, Colebrook-White, Panhandle or the General Flow Equations. Branch piping and Pipe loops may be modeled. AGA or Standing-Katz method for Z factor. Calculates capital and operating costs and transportation tariff. Version 6.0 - Graphically build pipeline model
 

 
LPIPE (aka LIQTHERM-Lite) is a hydraulic simulation software for liquid pipelines under isothermal flow. It calculates the steady state hydraulics of a liquid pipeline with multiple pump stations. Up to 5 pump stations with pumps in series or parallel at each station may be modeled.
 

 
LIQPROP calculates the specific gravity, viscosity, compressibility factor and bulk modulus of petroleum products at various temperatures, pressures and blended compositions. It also converts specific gravity to API gravity and vice versa, viscosity from SSU and SSF to centistokes. Viscosities and gravities of petroleum blends may be quickly calculated.
 

 
GASPROP calculates the physical and thermodynamic properties of a natural gas mixture, given the compositional data. You can input the mole percentage composition of each component in the natural gas mixture, such as 85% methane, 10% ethane, etc. and Gasprop will calculate the apparent molecular weight and gravity(relative to air =1.00) of the natural gas mixture, along with other properties such as viscosity, specific heats, Cp and Cv, the ratio Cp/Cv, and the Compressibility factor Z at a specified temperature and pressure. The latter can be calculated using one of the various methods, such as Standing and Katz, AGA method, etc. The built-in database of gas component properties can be updated by the user.
 

 
GPIPE is a hydraulic simulation software for gas pipelines. This is a scaled down version of GASMOD described above. Up to 5 compressor stations can be modeled.
 

 
PUMPCALC analyzes centrifugal pump performance for single and multiple pumps. Performs Viscosity Correction using Hydraulic Institute method. Predicts the performance of a centrifugal pump at different impeller diameter and speeds. Uses the affinity laws for centrifugal pumps. Models pumps in series and parallel configurations. Calculates the system head curves for a pipeline or uses system curve data input to determine the point of intersection of the combined pump curve and system head curve.
 

 
QPCalc can be used for quickly calculating the pressure drop in a pipe segment. Valves, fitting and custom pressure drop devices can be included. Use QPCalc to determine pressure drops in plant piping consisting of pipe segments, block valves, control valves, filters, strainers etc. All K-factors and equivalent lengths of valves, fittings and custom devices are included in a built-in database. No more charts, graphs or nomograms to use! Various pressure drop formulas such as Colebrook-White, Moody, Hazen-Williams, MIT, Miller and the T.R. Aude equation are included. QPCalc also tells you how much horsepower is required for a given flow rate
 

 
QPCalc-Gas can be used for quickly calculating the isothermal pressure drop or gas flow rate in a pipe segment. English and SI-Metric units are handled. Given the pipe inlet pressure, the outlet pressure can be calculated along with the line pack. Various pressure drop formulas are available to choose from, such as AGA Turbulent, Colebrook-White, Darcy-Weisbach, General Flow Equation, IGT, Panhandle A or B and Weymouth equation. Three options are available for compressibility factor calculations: Standing-Katz, AGA NX-19 and CNGA methods.
 

 
CURVEFIT is a software program for fitting experimental data to various polynomials, splines, and interpolating functions.
