1. For the system shown below, calculate the power supplied to the pump if its efficiency is 82%. Methyl alcohol at 25°C is flowing at the rate of 50m³/hour. The suction line is a standard DN100 schedule 40 steel pipe, 15m long. The total length of DN50 schedule 40 steel pipe in the discharge line is 180m. Assume that the entrance from reservoir 1 is through a square-edged inlet and that the elbows are standard. The valve is a fully open globe valve. 12m Discharge line DN 50 schedule 40 steel Pump Suction line Fully open globe valve DN 100 schedule 40 steel Flow Standard elbows (2)
