In order to design an Westco-pump, applying the theoretical formulae derived in last reports, the estimation of the turbulent coefficient k is required. In this report, several factors which affect the value of k are discussed both theoretically and experimentally. Firstly the effects of size and form of impeller and water passage on k are determined by experiments. Secondly the theoretical formula of internal leakage is derived and verified experimentally, since this quantity also affects the apparent value of k. Thirdly on the torque of the pump, the author applies the theoretical equation to many experiments and estimates the values of correction coefficient, which is a function of the apparent value of k. Lastly the cavitation of pump is studied. which occurs at high speed and high suction head of pump.
