20. A pump and pipeline system shown in Figure P20 delivers water at a temperature of 4°C

from reservoir A to B. The water surface elevation in reservoir A is 70.0 m, and the water

surface elevation in reservoir B is 120.0 m. The pipe has a length of L=3120 m, diameter

of D = 0.750 m, and a Darcy-Weisbach friction factor of f-0.017. Ignore minor losses.

The pump characteristic curve for a single pump is shown in Figure P19.

a) What is the total flow rate through the system?

b) What is the total head added to the system?

c) What is the flow rate through a single pump?

d) What is the head added by a single pump?
