## What is Ram efficiency?

Ram efficiency is defined as the ratio of the actual rise in pressure and isentropic rise in static pressure.

## How to Calculate Ram Efficiency?

Ram Efficiency calculator uses Ram Efficiency=(Stagnation Pressure-Initial Pressure of System)/(Final Pressure of System-Initial Pressure of System) to calculate the Ram Efficiency, Ram Efficiency = (stagnation_pressure - initial pressure)/( final pressure - initial pressure) Initial and final pressures are the pressures at the start and end of the ramming process. Ram Efficiency and is denoted by η symbol.

How to calculate Ram Efficiency using this online calculator? To use this online calculator for Ram Efficiency, enter Initial Pressure of System (Pi), Final Pressure of System (Pf) and Stagnation Pressure (p') and hit the calculate button. Here is how the Ram Efficiency calculation can be explained with given input values -> 333333.2 = (3000000-1)/(10-1).

### FAQ

What is Ram Efficiency?
Ram Efficiency = (stagnation_pressure - initial pressure)/( final pressure - initial pressure) Initial and final pressures are the pressures at the start and end of the ramming process and is represented as η=(p'-Pi)/(Pf-Pi) or Ram Efficiency=(Stagnation Pressure-Initial Pressure of System)/(Final Pressure of System-Initial Pressure of System). Initial Pressure of System is the total initial pressure exerted by the molecules inside the system, Final Pressure of System is the total final pressure exerted by the molecules inside the system and Stagnation Pressure is the pressure at the stagnation temperature during the process of ramming.
How to calculate Ram Efficiency?
Ram Efficiency = (stagnation_pressure - initial pressure)/( final pressure - initial pressure) Initial and final pressures are the pressures at the start and end of the ramming process is calculated using Ram Efficiency=(Stagnation Pressure-Initial Pressure of System)/(Final Pressure of System-Initial Pressure of System). To calculate Ram Efficiency, you need Initial Pressure of System (Pi), Final Pressure of System (Pf) and Stagnation Pressure (p'). With our tool, you need to enter the respective value for Initial Pressure of System, Final Pressure of System and Stagnation Pressure and hit the calculate button.
