Rocket Mass Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rocket Mass Ratio = e^(Change in Rocket Velocity/Rocket Exhaust Velocity)
M_R = e^(ΔV/V_e)
This formula uses 1 Constants, 3 Variables

Constants Used

e - Napier's constant Value Taken As 2.71828182845904523536028747135266249

Variables Used

Rocket Mass Ratio - Rocket Mass Ratio is the ratio of the rocket's wet mass (vehicle plus contents plus propellant) to its dry mass (vehicle plus contents).
Change in Rocket Velocity - (Measured in Meter per Second) - Change in rocket velocity is the difference between the initial velocity of the rocket to its final state velocity.
Rocket Exhaust Velocity - (Measured in Meter per Second) - Rocket exhaust velocity is the velocity of an exhaust stream after reduction by effects such as friction and pressure differences between the inside of the rocket and its surroundings.

STEP 1: Convert Input(s) to Base Unit

Change in Rocket Velocity: 0.17 Kilometer per Second --> 170 Meter per Second (Check conversion here)
Rocket Exhaust Velocity: 1.8 Kilometer per Second --> 1800 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_R = e^(ΔV/V_e) --> e^(170/1800)

Evaluating ... ...

M_R = 1.09904810320894

STEP 3: Convert Result to Output's Unit

1.09904810320894 --> No Conversion Required

FINAL ANSWER

1.09904810320894 ≈ 1.099048 <-- Rocket Mass Ratio

What is Rocket mass ?

"Rocket mass" typically refers to the mass of a rocket, which is the total weight of the entire vehicle, including the structure, propellant, payload, and any other components necessary for its operation.

How to Calculate Rocket Mass Ratio?

Rocket Mass Ratio calculator uses Rocket Mass Ratio = e^(Change in Rocket Velocity/Rocket Exhaust Velocity) to calculate the Rocket Mass Ratio, Rocket Mass Ratio is a measure of the efficiency of a rocket, it describes how much more massive the vehicle is with propellant than without; that is, the ratio of the rocket's wet mass (vehicle plus contents plus propellant) to its dry mass (vehicle plus contents). Rocket Mass Ratio is denoted by M_R symbol.

How to calculate Rocket Mass Ratio using this online calculator? To use this online calculator for Rocket Mass Ratio, enter Change in Rocket Velocity (ΔV) & Rocket Exhaust Velocity (V_e) and hit the calculate button. Here is how the Rocket Mass Ratio calculation can be explained with given input values -> 1.099048 = e^(170/1800).

FAQ

What is Rocket Mass Ratio?

Rocket Mass Ratio is a measure of the efficiency of a rocket, it describes how much more massive the vehicle is with propellant than without; that is, the ratio of the rocket's wet mass (vehicle plus contents plus propellant) to its dry mass (vehicle plus contents) and is represented as M_R = e^(ΔV/V_e) or Rocket Mass Ratio = e^(Change in Rocket Velocity/Rocket Exhaust Velocity). Change in rocket velocity is the difference between the initial velocity of the rocket to its final state velocity & Rocket exhaust velocity is the velocity of an exhaust stream after reduction by effects such as friction and pressure differences between the inside of the rocket and its surroundings.

How to calculate Rocket Mass Ratio?

Rocket Mass Ratio is a measure of the efficiency of a rocket, it describes how much more massive the vehicle is with propellant than without; that is, the ratio of the rocket's wet mass (vehicle plus contents plus propellant) to its dry mass (vehicle plus contents) is calculated using Rocket Mass Ratio = e^(Change in Rocket Velocity/Rocket Exhaust Velocity). To calculate Rocket Mass Ratio, you need Change in Rocket Velocity (ΔV) & Rocket Exhaust Velocity (V_e). With our tool, you need to enter the respective value for Change in Rocket Velocity & Rocket Exhaust Velocity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
