Velocity Coefficient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity Coefficient = Actual Exit Velocity/Ideal Exit Velocity
C_v = C_act/C_ideal
This formula uses 3 Variables

Variables Used

Velocity Coefficient - Velocity Coefficient is the ratio of the actual exit velocity to the ideal exit velocity.
Actual Exit Velocity - (Measured in Meter per Second) - Actual exit velocity is the velocity at the exit of nozzle, it includes losses due to external factors.
Ideal Exit Velocity - (Measured in Meter per Second) - Ideal Exit Velocity is the velocity at the exit of nozzle, it does not includes losses due to external factors.

STEP 1: Convert Input(s) to Base Unit

Actual Exit Velocity: 153 Meter per Second --> 153 Meter per Second No Conversion Required
Ideal Exit Velocity: 199 Meter per Second --> 199 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_v = C_act/C_ideal --> 153/199

Evaluating ... ...

C_v = 0.768844221105528

STEP 3: Convert Result to Output's Unit

0.768844221105528 --> No Conversion Required

FINAL ANSWER

0.768844221105528 ≈ 0.768844 <-- Velocity Coefficient
