H_i = ((V_f1/K_f)^2)/(2*g)
This formula uses 4 Variables

Variables Used

Head at Inlet of Francis Turbine - (Measured in Meter) - Head at Inlet of Francis Turbine is defined as the height of the water column at the inlet of the Francis turbine. It represents the energy of fluid at the inlet.
Velocity of Flow at Inlet of Francis Turbine - (Measured in Meter per Second) - The Velocity of Flow at Inlet of Francis Turbine is the flow velocity of the fluid at the inlet or the entry of a francis turbine.
Flow Ratio of Francis Turbine - Flow Ratio of Francis Turbine is the ratio of flow velocity at the exit to the theoretical jet velocity.
Acceleration Due to Gravity - (Measured in Meter per Square Second) - Acceleration Due to Gravity is acceleration gained by an object because of gravitational force.

STEP 1: Convert Input(s) to Base Unit

Velocity of Flow at Inlet of Francis Turbine: 2.3 Meter per Second --> 2.3 Meter per Second No Conversion Required
Flow Ratio of Francis Turbine: 0.16 --> No Conversion Required
Acceleration Due to Gravity: 9.81 Meter per Square Second --> 9.81 Meter per Square Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_i = ((V_f1/K_f)^2)/(2*g) --> ((2.3/0.16)^2)/(2*9.81)

Evaluating ... ...
