Problem 3 Water (20°C) is pumped through the 300-mm steel pipe from the lower tank to the upper one at a rate of 0.4 m³/s. Given that the pump efficiency is 65% and the pump is on for 5 hours each day, what will be the monthly (30 days) energy cost for the pump if the electricity rate is 0.5 USD per kWh? Assume α = 1.0 throughout. Elevation=235 m 10 m 50 m Elevation 200 m = 300 mm r = 300 mm 100 m
