Velocity Coefficient Solution

Follow our step by step solution on how to calculate Velocity Coefficient?

FIRST Step Consider the formula

C v = \frac{C act}{C ideal}

Next Step Substitute values of Variables

∴

C v = \frac{153m/s}{199m/s}

Next Step Prepare to Evaluate

∴

C v = \frac{153}{199}

Next Step Evaluate

∴

C v = 0.768844221105528

LAST Step Rounding Answer

∴

C v = 0.7688

Velocity Coefficient

Velocity Coefficient is the ratio of the actual exit velocity to the ideal exit velocity.

Symbol: C_v

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Velocity Coefficient

Actual Exit Velocity

Actual exit velocity is the velocity at the exit of nozzle, it includes losses due to external factors.

Symbol: C_act

Measurement: SpeedUnit: m/s

Note: Value should be greater than 0.

Formulas to find Actual Exit Velocity

Ideal Exit Velocity

Ideal Exit Velocity is the velocity at the exit of nozzle, it does not includes losses due to external factors.

Symbol: C_ideal

Measurement: SpeedUnit: m/s

Note: Value should be greater than 0.
