Problem #7(30points! A motor- driven pump reservoir, through a 2500m long, 30 cm ID plastic level in the second re en centrifugal pump delivers 15°C water at the rate of 10m3/min from a pipe, to a second reservoir. The water servoir is 40 m above the water level in the first reservoir. The pump efficiency is 75%. The loss coefficient of the square-edged entrance is 0.5 a) Sketch the problem and locate your point 1 and 2(2points) b) Find the velocity of the water in the pipe. (2 points) c) Find the head losses of the minor losses? (4points) d) Name the equation used to find the head losses for the major losses? (2po e) What is the value of the friction ints) losses f? Show your work in the chart used. (8 points) t) Name this chart? (2points) g) Find the head added by the pump. (7 points) h) Find the motor power of the pump at this efficiency. (3points)
