Mass Ratio of Rocket Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mass Ratio = Final Mass/Initial Mass
MR = mf/m0
This formula uses 3 Variables
Variables Used
Mass Ratio - Mass Ratio is the ratio of mass in the rocket.
Final Mass - (Measured in Kilogram) - Final Mass represents the final mass of the rocket (after expelling propellant).
Initial Mass - (Measured in Kilogram) - Initial Mass often refers to the mass of a spacecraft or rocket at the start of a mission, including all components such as payload, structure, propellant, and any other necessary equipment.
STEP 1: Convert Input(s) to Base Unit
Final Mass: 22 Kilogram --> 22 Kilogram No Conversion Required
Initial Mass: 15 Kilogram --> 15 Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
MR = mf/m0 --> 22/15
Evaluating ... ...
MR = 1.46666666666667
STEP 3: Convert Result to Output's Unit
1.46666666666667 --> No Conversion Required
FINAL ANSWER
1.46666666666667 1.466667 <-- Mass Ratio

9 Theory Of Rockets Calculators

Rocket Exhaust Gas Velocity
​ Go 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
​ Go 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
​ Go Effective Exhaust Velocity = Jet Velocity+(Nozzle Exit Pressure-Atmospheric Pressure)*Exit Area/Propellant Mass Flow Rate
Throat Velocity of Nozzle
​ Go Throat Velocity = sqrt((2*Specific Heat Ratio)/(Specific Heat Ratio+1)*[R]*Temperature at Chamber)
Velocity Increment of Rocket
​ Go Velocity Increment of Rocket = Jet Velocity of Rocket*ln(Initial Mass of Rocket/Final Mass of Rocket)
Structural Mass Fraction
​ Go Structural Mass Fraction = Structural Mass/(Propellant Mass+Structural Mass)
Payload Mass Fraction
​ Go Payload Mass Fraction = Payload Mass/(Propellant Mass+Structural Mass)
Propellent Mass Fraction
​ Go Propellant Mass Fraction = Propellant Mass/Initial Mass
Mass Ratio of Rocket
​ Go Mass Ratio = Final Mass/Initial Mass

Mass Ratio of Rocket Formula

Mass Ratio = Final Mass/Initial Mass
MR = mf/m0

What is Mass in Rocket ?

Mass refers to the total amount of matter comprising the rocket, including all its components such as the structure, payload, propellant, engines, and any other equipment carried onboard.

How to Calculate Mass Ratio of Rocket?

Mass Ratio of Rocket calculator uses Mass Ratio = Final Mass/Initial Mass to calculate the Mass Ratio, The Mass Ratio of Rocket formula is the ratio of its initial mass (including propellant) to its final mass (after expelling propellant), it is an essential concept in rocket design because it directly impacts the performance characteristics of the rocket. It affects factors such as the achievable velocity, payload capacity, and efficiency of the rocket. Mass Ratio is denoted by MR symbol.

How to calculate Mass Ratio of Rocket using this online calculator? To use this online calculator for Mass Ratio of Rocket, enter Final Mass (mf) & Initial Mass (m0) and hit the calculate button. Here is how the Mass Ratio of Rocket calculation can be explained with given input values -> 1.466667 = 22/15.
