A double suction, single stage, centrifugal pump delivers 950m /hr of sea water (SG=1.03) from a source where the water level varies 2m from high tide to low tide. The pump centerline is located 2.6m above the surface of the water at high tide level. The pump discharges into a surface condenser, 3m above pump centerline. Loss of head due to friction in suction pipe is 0.8m and that in the discharge side is 3m. Pump is directly coupled to a 1750 rpm, 460V, 3 phase, 60 Hz motor. Calculate the specific speed of pump in rpm.

3) The MITL ME laboratory has installed a double-suction, three-stage, centrifugal pump with a discharge of 330 gpm under 200 ft head and running at 1200 rpm. It is proposed to install another pump with double suction and six stages, but of the same characteristics, to operate at 98 ft head and deliver 430 gpm. Calculate a) the speed of the proposed pump; b) the impeller diameter of the proposed pump if the diameter of the existing pump is 6 inches; and c) the type of the existing and the proposed pump.
Calculate the available suction head height of the centrifugal pump from the following data: (1) The atmospheric pressure is 730 V mm of mercury, (2) the head loss in the suction pipe (including friction loss and accessories loss, etc. is 2.95 meters, ( 3) The speed in the water suction pipe is 1.6m/sec, (4) the water temperature is 30°C.
An existing pump is used to pump water with the following data at BEP: D = 2.15 in, N = 1784 rpm, ρ = 998 kg/m3, Q = 18 gpm, H = 4.2 ft. A larger pump is to be designed based from the existing one to be used for pumping slurry (ρ = 1220 kg/m3) such that its best efficiency point occurs as close as possible to a volume flow rate of 48 gpm and at a net head of 15 ft. Calculate the new pump diameter in inches. Round off your final answer to 3 decimal places.
