This formula uses 6 Variables
Variables Used
Effective Exhaust Velocity - (Measured in Meter per Second) - Effective exhaust velocity is the velocity of a rocket's exhaust relative to the rocket.
Jet Velocity - (Measured in Meter per Second) - Jet Velocity is the effective exhaust velocity.
Nozzle Exit Pressure - (Measured in Pascal) - The Nozzle Exit Pressure in rocketry refers to the pressure of the exhaust gases at the exit of the rocket engine nozzle.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as air pressure or barometric pressure, is the force per unit area exerted by the weight of the Earth's atmosphere above a given point.
Exit Area - (Measured in Square Meter) - The Exit Area in rocketry refers to the cross-sectional area at the exit of the rocket engine nozzle, where the exhaust gases are expelled into the surrounding environment.
Propellant Mass Flow Rate - (Measured in Kilogram per Second) - The Propellant Mass Flow Rate refers to the amount of mass that flows through a given point in the rocket propulsion system per unit time.
STEP 1: Convert Input(s) to Base Unit
Jet Velocity: 2151.8 Meter per Second --> 2151.8 Meter per Second No Conversion Required
Nozzle Exit Pressure: 1.24 Megapascal --> 1240000 Pascal (Check conversion ​here)
Atmospheric Pressure: 0.1013 Megapascal --> 101300 Pascal (Check conversion ​here)
Exit Area: 1.75 Square Meter --> 1.75 Square Meter No Conversion Required
Propellant Mass Flow Rate: 11.32 Kilogram per Second --> 11.32 Kilogram per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
c = Ve+(p2-p3)*A2/ṁ --> 2151.8+(1240000-101300)*1.75/11.32
Evaluating ... ...

Rocket Exhaust Gas Velocity
Jet Velocity = sqrt(((2*Specific Heat Ratio)/(Specific Heat Ratio-1))*[R]*Temperature at Chamber*(1-(Nozzle Exit Pressure/Pressure at Chamber)^((Specific Heat Ratio-1)/Specific Heat Ratio)))
Total Velocity Required to Place Satellite in Orbit
Total Velocity of Rocket = sqrt(([G.]*Mass Of Earth*(Radius of Earth+2*Height of Satellite))/(Radius of Earth*(Radius of Earth+Height of Satellite)))
Effective Exhaust Velocity of Rocket
Effective Exhaust Velocity = Jet Velocity+(Nozzle Exit Pressure-Atmospheric Pressure)*Exit Area/Propellant Mass Flow Rate
Throat Velocity of Nozzle
Throat Velocity = sqrt((2*Specific Heat Ratio)/(Specific Heat Ratio+1)*[R]*Temperature at Chamber)
Velocity Increment of Rocket
Velocity Increment of Rocket = Jet Velocity of Rocket*ln(Initial Mass of Rocket/Final Mass of Rocket)
Structural Mass Fraction
Structural Mass Fraction = Structural Mass/(Propellant Mass+Structural Mass)
Propellent Mass Fraction
Propellant Mass Fraction = Propellant Mass/Initial Mass
Mass Ratio of Rocket
Mass Ratio = Final Mass/Initial Mass

## What is Exhaust Velocity ?

The exhaust velocity of a rocket, often, refers to the velocity at which the exhaust gases are expelled from the rocket engine nozzle. It represents the speed at which the propellant gases leave the rocket, generating thrust according to Newton's third law of motion: for every action, there is an equal and opposite reaction.

## How to Calculate Effective Exhaust Velocity of Rocket?

Effective Exhaust Velocity of Rocket calculator uses Effective Exhaust Velocity = Jet Velocity+(Nozzle Exit Pressure-Atmospheric Pressure)*Exit Area/Propellant Mass Flow Rate to calculate the Effective Exhaust Velocity, The Effective Exhaust Velocity of Rocket is the velocity of an exhaust stream after reduction by effects such as friction, non-axially directed flow, and pressure differences between the inside of the rocket and its surroundings. Effective Exhaust Velocity is denoted by c symbol.
