Things like turbine power plants or automobile engines produce “work” in the sense that they “produce” a shaft that is rotating at a given speed and is capable of rotating at that speed while delivering a given torque. incarnation\u0027s 8t
How are the turbopumps on a typical pump driven rocket engine
WebTurbomolecular pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. In a turbomolecular pump, a rapidly spinning turbine rotor 'hits' gas molecules from the inlet of the pump towards the exhaust in order to create or maintain a vacuum. Web1 Answer Sorted by: 4 According to the monograph NASA SP-8107 Turbopump Systems for Liquid Rocket Engines (table II) : The F1 fuel (RP-1) pump had an inlet pressure of 45 psi and an outlet pressure of 1856 psi. The J2 fuel (Hydrogen) pump had an inlet pressure of 30 psi and an outlet pressure of 1238 psi. Share Improve this answer Follow WebDec 27, 2015 · It is simply that the rocket operates at much higher temperatures than gas turbines do. This translates to more thrust at the greater temperatures. Turbine blades in turbojets would melt at such high temperatures. Rockets cool the outer lining of the rocket combustion chamber. inclusive green growth
