1) Water at 60 oF is flowing in a 6-in schedule 40 steel pipe that is 100 ft long. Calculate the maximum allowable volume flow rate if the energy loss due to pipe friction is to be limited to 180 ft-lb/lb.
2) Determine the required size of new schedule 40 steel pipe to carry water at 60 oF with a maximum pressure drop of 16 psi per 1200 ft when the rate rate 0.8 ft3/s.
