Question

VI-4) A pump having a displacement of 14 [cm³/rev] is driven at 1440 [rpm] and operates against a maximum pressure of 150 [bar]. The volumetric efficiency is 0.90 and the overall efficiency is 0.80. Calculate a) The pump delivery in [L/min]. b) The input power required at the pump shaft in [kW]. c) The drive torque at the pump shaft in [N/m]. Ans.: a) 18.1 [L/min], b) 5.7 [kW], c) 37.7 [Nm].
