The Saturn F-1 engine combined kerosene with oxygen; the chemical combustion forced gas out of the rocket nozzle with a speed of roughly exhaust speed u = 2600 m/s Q: How many kg of fuel did the F-1 engine burn each second?
The Saturn F-1 combined a relatively small engine with gigantic fuel tanks. How big were the tanks? Well, compare the mass of the system when the tanks were full to the mass when the tanks were empty: mass (full of fuel) = 436,000 kg mass (out of fuel) = 26,600 kg Q: Suppose a Saturn F-1 engine in deep space with a full set of fuel tanks was just floating, motionless. If the engine is ignited, and all the fuel processed, how fast would the empty engine be moving afterward? This is called the delta-vee of a rocket engine.
