Pressure in Combustion Chamber Rocket Engine/Motor

In order to calculate the pressure in the combustion chamber of a rocket engine we must have the value of the mass flow in lbm/sec.

 

 

Furthermore, the value of the Temperature, T0 is required in degree Rankine.

 

The default value of R used in the calculation is,

R = 2400 ft.lb/slug.R

and the Value of the gamma = 1.21

 

We also require to input the Throat Area of Rocket Engine, A* in ft^2.

 

Performing the calculation gives us the value of the Pressure in the Combustion Chamber, P0
