Variables Used

Eddy Loss - Eddy Loss is the loss in fluid current whose flow direction differs from that of the general flow; the motion of the whole fluid is the net result of the movements of the eddies that compose it.
Mean Velocity at End Sections at (1) - (Measured in Meter per Second) - Mean Velocity at End Sections at (1) is denoted by V₁ symbol.
Acceleration due to Gravity - (Measured in Meter per Square Second) - Acceleration due to Gravity is acceleration gained by an object because of gravitational force.
Mean Velocity at End Sections at (2) - (Measured in Meter per Second) - Mean Velocity at End Sections at (2) is the time average of the velocity of a fluid at a fixed point, over a somewhat arbitrary time interval counted from fixed time.

STEP 1: Convert Input(s) to Base Unit

Mean Velocity at End Sections at (1): 10 Meter per Second --> 10 Meter per Second No Conversion Required
