An attempt has been made to account for the scale effects observed when comparing the suction performance of a pump with that predicted from model tests by considering the thermodynamic aspects of cavitation. However, although improvements in the prediction of performance may be obtained in some cases by using the equation developed, these aspects do not account for all the scale effects observed.
