Water at 80°C is being pumped to a large reservoir 8.5 m above the discharge of the pump. The pipe network transporting the water is shown in Figure P4.26. The volumetric flow rate of the water is 10 L/s.

a. Specify the nominal diameter of the check valve.

b. Determine the pump head required to move the water through the system at the given flow rate (m).
