Kinetic Energy of Exhaust Gases Solution

STEP 0: Pre-Calculation Summary

Formula Used

Kinetic Energy of Gas = 1/2*Ideal Mass Flow Rate*(1+Fuel to Air Ratio)*Ideal Exit Velocity^2
KE = 1/2*m_i*(1+f)*C_ideal^2
This formula uses 4 Variables

Variables Used

Kinetic Energy of Gas - (Measured in Joule) - Kinetic Energy of Gas is energy present in the gases flowing out of the nozzle.
Ideal Mass Flow Rate - (Measured in Kilogram per Second) - Ideal Mass Flow Rate is the mass of air going out of the nozzle when no loss is considered.
Fuel to Air Ratio - Fuel to Air Ratio is the ratio of the mass of fuel to the mass of air during combustion. It dictates the efficiency of the combustion and the performance of the engine.
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

Ideal Mass Flow Rate: 5 Kilogram per Second --> 5 Kilogram per Second No Conversion Required
Fuel to Air Ratio: 0.005 --> 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

KE = 1/2*m_i*(1+f)*C_ideal^2 --> 1/2*5*(1+0.005)*199^2

Evaluating ... ...

KE = 99497.5125
