Water at 10°C flows through the system shown in the figure below at 0.34 m/s. Energy loss in the 40-cm pipe is negligible. Energy loss in the 30-cm pipe is known to be 1.5V2.A mercury manometer indicates that the absolute pressure at the top of the 30-cm pipe is 749.5 mm Hg abs. The pressure of the surroundings is 101,330 Pa. Calculate the power input to the pump.

Question

Please help get the correct answer. I tried doing it but it still says it's wrong. The first time I entered 59.09Kw and it said wrong. The second time after redoing my calculations I found 53.0899Kw but it still says wrong. Please help solve for the correct value. Thanks!

 

X Your answer is incorrect. Water at 10°C flows through the system shown in the figure below at 0.34 m/s. Energy loss in the 40-cm pipe is negligible. Energy loss in the 30-cm pipe is known to be 1.5V2. A mercury manometer indicates that the absolute pressure at the top of the 30-cm pipe is 749.5 mm Hg abs. The pressure of the surroundings is 101,330 Pa. Calculate the power input to the pump. p = 749.5 mm Hg Elevation 10 m- D = 30 cm -Elevation = 6 m 40-cm diameter Water T = 10 °C Elevation = 2 m W = i 53.0899 kW
