The 3PIPES programs compute liquid, gas or steam flow pressure drop in a single pipe, or flow distribution in 1, 2 or 3 parallel pipes of different materials and lengths connected at both ends. Valves and fittings entries from 1/8” to 150” with roughness values for steel, copper, cast iron, corrugated and riveted steel, cement, plastic and glass pipe materials. The 3PIPESLiquid (English and Metric Units) program includes elevation changes and viscosity conversions for liquids and specific gravity for API oils. The 3PIPESWasteWater program computes any liquid non-pressurized flow in partially full pipes. The 3PIPESGas program includes steam and 15 common gases at any velocity and pressure.
