How do the momentum and pressure terms in the thrust equation vary between an over- expanded, optimally expanded, and under-expanded nozzle? Why are the characteristic velocity (c*) and thrust coefficient (C used to compare rocket performance? What factors affect these two parameters? Why a bell-shaped nozzle performs better than a conical nozzle rocket. Give several reasons?

4. The discharge pressure gauge reading is 5 lb/in2 (psi) for the pumping system shown in the sketch below, with the outlet nozzle discharging a 2-inch diameter stream of water directly to the atmosphere. The gauge pressure at the pump suction inlet at the point of incipient cavitation is (-2,071.12) lb/ft, i.e., for vapor pressure of water at 68° F of 50.54 lb/ft2 absolute, and standard atmospheric pressure 30 in Hg. Friction losses in the suction piping from the reservoir...
