With this app you can calculate the pressure drop due friction losses in pipes and "minnor losses" due fittings and Hydrostatic Head for incompressible fluids and compressible fluids flow. NOW: GASES and LIQUIDS Included Δ Lost in pipes due to friction Δ Loss in fittings and valves Δ Hydrostatic pressure loss Also it contains tables: Δ fluid properties: Density and Viscosity Δ Roughness for different materials Δ Loss coefficient "K" for accessories Δ Viscosity Δ Specific Gravity (Gas and Liquids) SI and Imperial Units selection Note: Use decimal Point
