A single acting reciprocating pump operating at 140 rpm has a piston diameter of 220mm and stroke of 350 mm. The suction and delivery heads are 5 m and 22 m,respectively. If the efficiency of both suction and delivery strokes is 85 percent, then thekW. (upto three decimal places). ( Take ywaterpower required by the pump will be= 9810 N/m³).

2. A pump is used to transfer water from tank A to tank C through a pipeline that passes through point B. The AB pipeline experiences a head loss of 10m. Please, determine the power required by the pump and to draw an energy line that represents the state of energy of the water in the pipeline. It is assumed that any minor losses can be ignored, and the pump's efficiency is given as n=0.70. 50m A D₁-300mm L₁=1000m f=0.020 P B D₂=250mm L₂=2000m f 0.020 C 80m
Determine the shaft horsepower for an 80% efficient pump to discharge 30L/s through the system. The system losses, exclusive of pump losses, are 12V2/2g and H = 16m. Ans: 8.75hp H 150mm dia
A four-stage (parallel) pump delivers 15 m3 1950 rpm. It is desired to construct a pump at a certain number of stages in series that should run at 1450 rpm delivering 18m/min with 280m of head in total. What should be the new diameter of the impeller and number of stages? per minute of liquid. The total head obtained is 27m. Initially, the impeller measures 24cm in diameter running at
the 9.63. When glycerin (25°C or 77°F) flows through a 30 m (100 ft) length of 75 mm (3 in.) pipe, the head loss is 36 m (120 ft). Calculate the flowrate. 9.64. A pump of what power is required to pump 40 1/min of crude oil from a tank of surface elevation 12 to one of elevation 18 through 450 m of 75 mm pipe, if the oil is at (a) 25°C, (b) 40°C?
For water supply of a town, water is pump from a river 3 km away into a reservoir is 20 m. The population of the town is 50000 and per capita water demand is 120 litre/day. If the pump are to be operate for a total of 8 hours and the efficiency of pump is 80%, determined the horse power of the pump. Assume friction factor as 0.03, the velocity of flow as 2 m/s, and maximum daily demand as 1.5 times the average daily demand.
