Calculation Formula

Exhaust Velocity (Ve) = √(2 * Isp * g)

Where:
Ve = Exhaust Velocity (m/s)
Isp = Specific Impulse (s)
g = Gravitational Acceleration (m/s²)

Learn how to use the Exhaust Velocity Calculator and its working principles

How to Use the Calculator

  1. Enter the specific impulse (Isp) of the engine in seconds (s).
  2. Enter the gravitational acceleration (g) in meters per second squared (m/s²). The default value is 9.81 m/s², which represents Earth's standard gravity.
  3. Click the "Calculate" button to compute the exhaust velocity.
  4. The result will be displayed in meters per second (m/s).

Understanding Specific Impulse (Isp)

Specific impulse is a measure of the efficiency of a rocket engine. It represents the total impulse (change in momentum) per unit of propellant. The higher the specific impulse, the more efficient the engine.

Understanding Gravitational Acceleration (g)

Gravitational acceleration is the acceleration experienced by an object due to gravity. It varies depending on the location, but 9.81 m/s² is the standard value for Earth's surface.

Working Principle

The exhaust velocity is calculated using the formula: Ve = √(2 * Isp * g). This formula shows that the exhaust velocity is directly proportional to the square root of the specific impulse and the gravitational acceleration.
