How to Calculate Diffuser Efficiency given Inlet and Exit Velocities?
Diffuser Efficiency given Inlet and Exit Velocities calculator uses Diffuser Efficiency = Actual Static Pressure Rise/(Density of Air/2*(Inlet Velocity to Diffuser^2-Exit Velocity to Diffuser^2)) to calculate the Diffuser Efficiency, Diffuser Efficiency given Inlet and Exit Velocities is defined as the ratio of static pressure rise in actual process to the static pressure rise in the isentropic process when the latter is taken in terms of change in kinetic energy. Diffuser Efficiency is denoted by ηd symbol.
How to calculate Diffuser Efficiency given Inlet and Exit Velocities using this online calculator? To use this online calculator for Diffuser Efficiency given Inlet and Exit Velocities, enter Actual Static Pressure Rise (ΔP), Density of Air (ρ), Inlet Velocity to Diffuser (C1) & Exit Velocity to Diffuser (C2) and hit the calculate button. Here is how the Diffuser Efficiency given Inlet and Exit Velocities calculation can be explained with given input values -> 0.969106 = 39/(1.293/2*(80^2-79.61^2)).
