Solution to T1 by Waitz. (Unified Thermodynamics) Below is a schematic diagram of a helium-pressurized, bipropellant rocket engine system (for the fourth stage of the Peacekeeper ballistic missile). Describe the conversions of energy (internal, potential, kinetic and chemical) and exchanges of heat and work for this system and that of the rocket itself. Note at which points in the process heat is transferred to/from the surroundings. (LO#1, LO#2, LO#3) It is understood at this point in Unified that you have only had one or two lectures on thermodynamics, and no propulsion and fluid mechanics lectures. So what is expected is that you recognize conversions between various forms of energy when they occur and know then difference between transfers of energy called “work” and transfers of energy called “heat”. For the gases in the system, changes in potential energy will typically be small compared to the changes in internal energy, kinetic energy and chemical energy due to their low density.
