一般注記It was required that high pressure cryogenic pump efficiency be measured with great accuracy. If ordinary measurement apparatuses, such as a torque meter, are used, the pump rotor assembly becomes so complicated that the designed rotational speed may not be achieved. In order to solve this problem, research was done on whether the adiabatic efficiency, which has been used with compressors, could be applied to a high pressure cryogenic pump. The adiabatic efficiency is calculated using some enthalpies which are obtained by measuring pressures and temperatures at both pump inlet and outlet. A simple calculation was made in order to compare the ordinary efficiency with the adiabatic efficiency and show how to correct the adiabatic efficiency. It has been made clear that the adiabatic efficiency can be experimentally obtained with fairly small uncertainties.
