## Pressure head in terms of Flow ratio in Francis turbine Solution

STEP 0: Pre-Calculation Summary
Formula Used
head = ((Velocity of flow at inlet/Flow ratio)^2)/(2*Acceleration Due To Gravity)
H = ((Vf1/Kf)^2)/(2*g)
This formula uses 3 Variables
Variables Used
Velocity of flow at inlet - Velocity of flow at inlet is the flow velocity at the inlet (Measured in Meter per Second)
Flow ratio- Flow ratio is ratio of flow velocity at exit to the theoretical jet velocity
Acceleration Due To Gravity - The Acceleration Due To Gravity is acceleration gained by an object because of gravitational force. (Measured in Meter per Square Second)
STEP 1: Convert Input(s) to Base Unit
Velocity of flow at inlet: 1 Meter per Second --> 1 Meter per Second No Conversion Required
Flow ratio: 1 --> No Conversion Required
Acceleration Due To Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
H = ((Vf1/Kf)^2)/(2*g) --> ((1/1)^2)/(2*9.8)
Evaluating ... ...
H = 0.0510204081632653
STEP 3: Convert Result to Output's Unit
0.0510204081632653 Meter --> No Conversion Required
