Discharge Coefficient given Flow Area Solution

STEP 0: Pre-Calculation Summary
Formula Used
Discharge Coefficient = Actual Nozzle Flow Area/Nozzle Throat Area
CD = Aact/Athroat
This formula uses 3 Variables
Variables Used
Discharge Coefficient - Discharge Coefficient is the ratio of flow rate at exit to flow rate at inlet.
Actual Nozzle Flow Area - (Measured in Square Meter) - Actual nozzle flow area is the effective one-dimensional flow area.
Nozzle Throat Area - (Measured in Square Meter) - Nozzle Throat Area is the area of cross section at the throat of nozzle where the flow attains sonic velocity.
STEP 1: Convert Input(s) to Base Unit
Actual Nozzle Flow Area: 41 Square Meter --> 41 Square Meter No Conversion Required
Nozzle Throat Area: 50 Square Meter --> 50 Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CD = Aact/Athroat --> 41/50
Evaluating ... ...
CD = 0.82
STEP 3: Convert Result to Output's Unit
0.82 --> No Conversion Required
FINAL ANSWER
0.82 <-- Discharge Coefficient

Reversible Nozzle Jet Velocity
Go Ideal Exit Velocity = sqrt(2*Specific Heat at Constant Pressure*Nozzle Temperature*(1-(Pressure Ratio)^((Specific Heat Ratio-1)/(Specific Heat Ratio))))
Kinetic Energy of Exhaust Gases
Go Kinetic Energy of Gas = 1/2*Ideal Mass Flow Rate*(1+Fuel to Air Ratio)*Ideal Exit Velocity^2
Jet velocity given temperature drop
Go Ideal Exit Velocity = sqrt(2*Specific Heat at Constant Pressure*Temperature Drop)
Discharge Coefficient given Mass Flow
Go Discharge Coefficient = Actual Mass Flow Rate/Ideal Mass Flow Rate
Discharge Coefficient given Flow Area
Go Discharge Coefficient = Actual Nozzle Flow Area/Nozzle Throat Area
Velocity Coefficient
Go Velocity Coefficient = Actual Exit Velocity/Ideal Exit Velocity
Ideal Exhaust Velocity given Enthalpy Drop
Go Ideal Exit Velocity = sqrt(2*Enthalpy Drop in Nozzle)
Velocity Coefficient given Nozzle Efficiency
Go Velocity Coefficient = sqrt(Nozzle Efficiency)
