An industrial oil (s.g. = =0.85) is flowing at 160 gallons per minute (gpm) in a system with the following details: SUCTION: Standard elbow and the pipe is 7 foot-long. DISCHARGE: Street type elbow and the pipe length is 42 feet. Neglecting losses due to the filter and the hydraulic press, compute: (a) The total energy loss due to friction (suction and discharge pipes) (b) The total energy loss due to minor losses (suction and discharge)

2. A centrifugal pump installation has been designed to discharge 0.126 m^3/s of brine (sp.gr. = 1.2). The suction pipe is 305 mm and is at the same level as the discharge pipe which is 203 mm in diameter. At the centerline of suction flange, the vacuum is 154.2 mm Hg. The discharge pressure gauge reads 0.1379 MPa and is connected 1.22 m above the discharge flange centerline. The pump is driven by a 35 KW electric motor that will not carry overload and has an efficiency of 82%. There is no significant head loss. The design conditions have changed, and is now desired to increase the capacity of the pump by increasing the speed. The motor is so designed that its speed maybe increased but its power cannot exceed its design rating. Assuming the pump efficiency to remain constant, how much can the pump capacity be increased without overloading the motor?
