MMSCMH (Million Standard Cubic Meter per Hour).SCCM (Standard Cubic Centimetres per Minute).Pipe Flow Wizard provides a choice of standard volume units for gas flow rate which include: Gas flow rates are therefore often referred to in terms of mass flow (weight of flow) or standard volume (which is the volume of gas at standard conditions, normally atmospheric pressure and some common temperature reference, since this standard volume also define a constant mass flow). Although the volume of gas and velocity in the pipe changes, the mass flow (weight of flow) in the pipe will remain constant. As the volume of gas increases, the velocity of the gas in the pipe will increase. The Pipe Flow Wizard software now contains a Compressible Isothermal Flow Calculation Engine (from version 2 and later).Īs pressure loss occurs along a pipe, the gas density will decrease and the volume of the gas will expand.
