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.
