1. What is the Gas Nozzle Momentum Formula?

The momentum formula p = m × v calculates the momentum of gas particles exiting a nozzle, where p represents momentum, m is mass, and v is velocity. This calculation is essential in fluid dynamics and propulsion systems.

2. How Does the Calculator Work?

The calculator uses the momentum equation:

Where:

• \( p \) — Momentum (kg·m/s)
• \( m \) — Mass (kg)
• \( v \) — Velocity (m/s)

Explanation: The equation calculates the quantity of motion of gas particles, which is directly proportional to both mass and velocity.

3. Importance of Momentum Calculation

Details: Accurate momentum calculation is crucial for designing efficient propulsion systems, understanding gas flow dynamics, and optimizing nozzle performance in various engineering applications.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. All values must be valid positive numbers.
