Exhaust Velocity of Kerosene
Burned with Liquid Oxygen or Hydrogen
Peroxide

Original contribution 2001
The following graphs show performance for kerosene burned with liquid oxygen or with hydrogen peroxide. Performance was calculated for expansion of the exhaust into a vacuum, and assumes chemical equilibrium to the throat of the engine, followed by “frozen flow” non-equilibrium conditions to the nozzle exit. Real world engines will have exhaust velocities of roughly 90 to 95% of these theoretical values.
If you wish
specific impulse rather than exhaust velocity, divide the exhaust velocity by
9.807 m/sec2 .
1 MPa = 145 psi
2 MPa = 290 psi
3 MPa
= 435 psi
4 MPa =
580 psi
