b) The old Hydraulics laboratory in Mechanical Engineering used a roof tank to supply apparatus with water at a nearly constant head. The water was collected in an under floor sump, and then pumped back to the roof tank after the experiment. The flow rate was 10 litre s1. The tank was 6m above the sump, and the length of the pipe route was 15 m. The old 6" pipes are now heavily corroded (k = 7.5 mm). The old pump has been scrapped. What head AH would be specified for a pump to restore the system using the old pipes? What would the pump power be? If the pipes were replaced with 150 mm diameter PVC pipes, what pump AH would be required? ROOF TANK 6m PUMP SUMP
