A pump with an efficiency of 88.8% lifts 3.2 m³ of water per minute to a height of 26 metres. An electrical motor having an efficiency of 87.7% drives the pump. The motor is connected to a 220-V dc supply. Assume that 1 m³ of water has a mass of 1000 kg. 2.1 Calculate the input power of the motor. [8] 2.2 Calculate the current drawn from the source. [2] 2.3 Calculate the electrical energy consumed in kWh when the motor runs at this load for eight hours. [2] For the toolhar i
