A brief description of the operation and analysis of a solar water pum
p is given. It is shown that one of the parameters affecting the perfo
rmance of the pump is the time taken for condensation of the working f
luid in each cycle. The condensation time in each cycle is determined
through heat transfer analysis of the condenser. The effects of inlet
water temperature and mass flow rate of the cooling water to the conde
nser on the condensation time and the pump performance have been studi
ed and discussed.
