Effective Exhaust Velocity

Loading author...

Convert rocket specific impulse into effective exhaust velocity, mass flow, and thrust power.

s

Exhaust velocity

3.24 km/s

3,236 m/s from Isp x g0

Mass flow

30.90 kg/s

100.0 kN divided by effective velocity

Jet power

161.81 MW

ideal kinetic power rate in the exhaust stream

Specific impulse to velocity

Specific impulse in seconds becomes an equivalent exhaust velocity when multiplied by standard gravity.

Effective velocity

3,236 m/s / 3.24 km/s

Mass-flow consequence

30.90 kg/s for 100.0 kN

higher effective velocity lowers propellant flow

Kinetic power check
