Angular Speed of Turbine given Specific Speed Solution

STEP 0: Pre-Calculation Summary

Formula Used

Speed of Turbine = (Specific Speed of Turbine*Effective Head of Turbine^(5/4))/sqrt(Power Output of Turbine)
N = (N_s*H_eff^(5/4))/sqrt(P)
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

Speed of Turbine - (Measured in Revolution per Minute) - Speed of Turbine is the angular velocity of the rotation of the turbine.
Specific Speed of Turbine - (Measured in Revolution per Minute) - Specific Speed of Turbine is the speed which produces 1KW of power under 1m head.
Effective Head of Turbine - (Measured in Meter) - Effective Head of Turbine is the net or the effective head of the turbine. It is the height difference between where the water enters the hydro system and where it leaves it.
Power Output of Turbine - (Measured in Kilowatt) - The Power Output of Turbine is the amount of energy transferred in unit time by the turbine.

STEP 1: Convert Input(s) to Base Unit

Specific Speed of Turbine: 159.4 Revolution per Minute --> 159.4 Revolution per Minute No Conversion Required
Effective Head of Turbine: 25 Meter --> 25 Meter No Conversion Required
Power Output of Turbine: 1986.5 Kilowatt --> 1986.5 Kilowatt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N = (N_s*H_eff^(5/4))/sqrt(P) --> (159.4*25^(5/4))/sqrt(1986.5)

Evaluating ... ...

N = 199.925892386439

STEP 3: Convert Result to Output's Unit

20.9361904917212 Radian per Second -->199.925892386439 Revolution per Minute (Check conversion here)

FINAL ANSWER

199.925892386439 ≈ 199.9259 Revolution per Minute <-- Speed of Turbine

(Calculation completed in 00.020 seconds)
