Flow Velocity given Rate of Flow through Propeller Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flow Velocity = (8*Rate of Flow/(pi*Diameter of Turbine^2))-Absolute Velocity of Issuing Jet
V_f = (8*q_flow/(pi*D^2))-V
This formula uses 1 Constants, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
Rate of Flow - (Measured in Cubic Meter per Second) - Rate of Flow is the rate at which a liquid or other substance flows through a particular channel, pipe, etc.
Diameter of Turbine - (Measured in Meter) - Diameter of Turbine is a typical turbine with a 600 kW electrical generator will typically have a rotor diameter of some 44 meters.
Absolute Velocity of Issuing Jet - (Measured in Meter per Second) - Absolute Velocity of Issuing Jet is actual velocity of jet used in propeller.

STEP 1: Convert Input(s) to Base Unit

Rate of Flow: 24 Cubic Meter per Second --> 24 Cubic Meter per Second No Conversion Required
Diameter of Turbine: 14.56 Meter --> 14.56 Meter No Conversion Required
Absolute Velocity of Issuing Jet: 6 Meter per Second --> 6 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_f = (8*q_flow/(pi*D^2))-V --> (8*24/(pi*14.56^2))-6

Evaluating ... ...

V_f = -5.71171064528699

STEP 3: Convert Result to Output's Unit

-5.71171064528699 Meter per Second --> No Conversion Required

FINAL ANSWER

-5.71171064528699 ≈ -5.711711 Meter per Second <-- Flow Velocity
