Water is pumped to a storage tank from a pool by a centrifugal pump. The elevation difference between the pool and the storage tank is 60 m. The stórage tank and the pool are open to atmosphere. 50 meters of 6 in Sc 40 steel pipe is used between pool and pump. After the pump 6 in Sc 40 pipe with a length of 22 m is suddenly contracted to 4 in Sc 40 pipe, that is 70 m. The flow rate of water is 2.5 m/min and the temperature is 20°C. If the pump efficiency is 0.6 and the cost of electrical energy is 0.40 TL/kWh,calculate daily cost of electricity used for this system

Question
Water is pumped to a storage tank from a pool by a centrifugal pump. The elevation
difference between the pool and the storage tank is 60 m. The stórage tank and the pool
are open to atmosphere. 50 meters of 6 in Sc 40 steel pipe is used between pool and
pump. After the pump 6 in Sc 40 pipe with a length of 22 m is suddenly contracted to
4 in Sc 40 pipe, that is 70 m. The flow rate of water is 2.5 m/min and the temperature
is 20°C. If the pump efficiency is 0.6 and the cost of electrical energy is 0.40
TL/kWh,calculate daily cost of electricity used for this system
