Jet Velocity given Theoretical Propulsive Efficiency Solution

STEP 0: Pre-Calculation Summary
Formula Used
Absolute Velocity of Issuing Jet = (2/Efficiency of Jet-1)*Flow Velocity
V = (2/η-1)*Vf
This formula uses 3 Variables
Variables Used
Absolute Velocity of Issuing Jet - (Measured in Meter per Second) - Absolute Velocity of Issuing Jet is actual velocity of jet used in propeller.
Efficiency of Jet - Efficiency of Jet is an electric motor is defined as the ratio of usable shaft power to electric input power.
Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
STEP 1: Convert Input(s) to Base Unit
Efficiency of Jet: 0.8 --> No Conversion Required
Flow Velocity: 5 Meter per Second --> 5 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
V = (2/η-1)*Vf --> (2/0.8-1)*5
Evaluating ... ...
V = 7.5
