Francis Turbine Flow Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flow Ratio of Francis Turbine = Velocity of Flow at Inlet of Francis Turbine/(sqrt(2*Acceleration Due to Gravity*Head at Inlet of Francis Turbine))
K_f = V_f1/(sqrt(2*g*H_i))
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Flow Ratio of Francis Turbine - Flow Ratio of Francis Turbine is the ratio of flow velocity at the exit to the theoretical jet velocity.
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.
Acceleration Due to Gravity - (Measured in Meter per Square Second) - Acceleration Due to Gravity is acceleration gained by an object because of gravitational force.
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.

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
Acceleration Due to Gravity: 9.81 Meter per Square Second --> 9.81 Meter per Square Second No Conversion Required
Head at Inlet of Francis Turbine: 10.5 Meter --> 10.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_f = V_f1/(sqrt(2*g*H_i)) --> 2.3/(sqrt(2*9.81*10.5))

Evaluating ... ...

K_f = 0.160244703899712

STEP 3: Convert Result to Output's Unit

0.160244703899712 --> No Conversion Required

FINAL ANSWER

0.160244703899712 ≈ 0.160245 <-- Flow Ratio of Francis Turbine
