There are two ways to calculate compressible flow with a calculator: using the compressible isothermal equation and using the Renouard formula. In the flow rate calculation scenario, the calculator calculates and shows the flow rate at standard conditions. If you are calculating pressure drop, the...
For the calculation of the friction factor the worksheet uses the Haaland equation which gives an implicit solution to the friction factor. The Wikipedia article on "Darcy friction factor formulae" states “The Haaland equation is used to solve directly for the Darcey-Weisbach friction factor f ...
The frictional pressure drop is described by Colebrook–Darcy–Weisbach formula, using friction factor λ and adopting hydraulic equivalent diameter dH as follows: (4.18)ΔPf=λL2dHρvl2 4.3.6.2.2.2 Pressure drop in two-phase flow region As for the model for the pressure drop prediction of eva...
Using a calculator with trigonometric functions or a trigonometric function table, find the arccosine (cos-1) θ of 0.7,which is 45.57 degrees. For this example, call this angle. STEP-3 //Find theimpedance (Z)corrected to0.7 power factor (Zc): ...

You can calculate pressure drops of gases with the same formula as liquids if the relativ change of density is low (change of density/density = 0.02). Have you such a case then it's possible to calculate the gases as liquids. Switch in the "Flow medium" window the condition button to ...
