Compressible gas flow - Pipe Flow Calculations

WebFriction factor calculation. Adiabatic compressible flow is the flow where no heat is transferred to or from pipe like in short, perfectly insulated pipe. The heat which is created due to flow friction is added to the flow and that amount of energy is actually acceptable. For adiabatic compressible flow is: WebThe method of equivalent lengths accounts for minor losses by converting each valve and fitting to the length of straight pipe whose friction loss equals the minor loss. The equivalent lengths vary by materials, manufacturer and size. The other method uses loss coefficients.
