Liquid rocket pumps were realised and tested for obtaining the cavitation and non-cavitation performance. Two pumps, one each for fuel and oxidiser were tested for obtaining the critical Net Positive Suction Head for ensuring the cavitation free operation of these pumps in flight. The experimentally obtained values of NPSH have been compared with the theoretical values obtained using the model developed by Stripling (1962). Based on this comparison it is possible to predict the propellant tank pressure in advance with some confidence. The final value of tank pressure can be revised later when more comprehensive experimental values are available.
