STEP 0: Pre-Calculation Summary
Formula Used
ηbm = (2*(Fl/Fd)-1)/(2*(Fl/Fd)+1)
This formula uses 2 Variables
Variables Used
Blade Lift Force - Blade Lift Force is the sum of all the forces acting on a blade that force it to move perpendicular to the direction of flow. (Measured in Newton)
Blade Drag Force - Blade Drag Force is the resisting force experienced by the blades moving through a fluid. (Measured in Newton)
STEP 1: Convert Input(s) to Base Unit
Blade Lift Force: 100 Newton --> 100 Newton No Conversion Required
Blade Drag Force: 60 Newton --> 60 Newton No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ηbm = (2*(Fl/Fd)-1)/(2*(Fl/Fd)+1) --> (2*(100/60)-1)/(2*(100/60)+1)
Evaluating ... ...
ηbm = 0.538461538461538
STEP 3: Convert Result to Output's Unit
0.538461538461538 --> No Conversion Required

## What is lift force and drag force?

A fluid flowing around an object exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction.
