Unit flow per discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Unit Discharge for Hydraulic Turbine = Discharge for Hydraulic Turbine/sqrt(Effective Head of Turbine)
Q_u = Q_ht/sqrt(H_eff)
This formula uses 1 Functions, 3 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

Unit Discharge for Hydraulic Turbine - (Measured in Cubic Meter per Second) - Unit Discharge for Hydraulic Turbine is the discharge or the outflow of the fluid from the turbine working at 1m head.
Discharge for Hydraulic Turbine - (Measured in Cubic Meter per Second) - Discharge for Hydraulic Turbine is the discharge or the flow of the fluid from the turbine that is operating.
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.

STEP 1: Convert Input(s) to Base Unit

Discharge for Hydraulic Turbine: 58.5 Cubic Meter per Second --> 58.5 Cubic Meter per Second No Conversion Required
Effective Head of Turbine: 25 Meter --> 25 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_u = Q_ht/sqrt(H_eff) --> 58.5/sqrt(25)

Evaluating ... ...

Q_u = 11.7

STEP 3: Convert Result to Output's Unit

11.7 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

11.7 Cubic Meter per Second <-- Unit Discharge for Hydraulic Turbine

Head of turbine given specific speed

Go Effective Head of Turbine = ((Speed of Turbine*sqrt(Power Output of Turbine))/Specific Speed of Turbine)^(4/5)

Specific Speed of Turbine

Go Specific Speed of Turbine = (Speed of Turbine*sqrt(Power Output of Turbine))/(Effective Head of Turbine^(5/4))

Angular Speed of Turbine given Specific Speed

Go Speed of Turbine = (Specific Speed of Turbine*Effective Head of Turbine^(5/4))/sqrt(Power Output of Turbine)

Power of Turbine given Specific Speed

Go Power Output of Turbine = ((Specific Speed of Turbine*Effective Head of Turbine^(5/4))/Speed of Turbine)^2

Unit flow per discharge

Go Unit Discharge for Hydraulic Turbine = Discharge for Hydraulic Turbine/sqrt(Effective Head of Turbine)

Unit power

Go Unit Power of Turbine = Power Output of Turbine/((sqrt(Effective Head of Turbine))^3)

Unit speed of turbomachine

Go Unit Speed of Turbine = Speed of Turbine/sqrt(Effective Head of Turbine)

Unit flow per discharge Formula

Unit Discharge for Hydraulic Turbine = Discharge for Hydraulic Turbine/sqrt(Effective Head of Turbine)
Q_u = Q_ht/sqrt(H_eff)
