How to Calculate Efficiency of draft tube?
Efficiency of draft tube calculator uses Efficiency of Draft Tube = ((((Velocity of Water at Inlet of Draft Tube^2)/(2*[g]))-((Velocity of Water at Outlet of Draft Tube^2)/(2*[g])))-(Loss of Head in Draft Tube))/((Velocity of Water at Inlet of Draft Tube^2)/(2*[g])) to calculate the Efficiency of Draft Tube, The Efficiency of draft tube formula is defined as the ratio of actual conversion of kinetic head into pressure head to the kinetic head at the inlet of the draft tube. Efficiency of Draft Tube is denoted by ηd symbol.
How to calculate Efficiency of draft tube using this online calculator? To use this online calculator for Efficiency of draft tube, enter Velocity of Water at Inlet of Draft Tube (V1), Velocity of Water at Outlet of Draft Tube (V2) & Loss of Head in Draft Tube (hf) and hit the calculate button. Here is how the Efficiency of draft tube calculation can be explained with given input values -> 0.905519 = ((((6^2)/(2*[g]))-((1.2^2)/(2*[g])))-(0.1))/((6^2)/(2*[g])).
