A single -acting reciprocal pump lifts a liquid of specific weight 7.50 kN/m³ from a pressurised storeage reservoir to an overhead container. The free surface in the supply reservoir is at an elevation of 5.0 m above the centre of the pump. The ambient pressure over the liquid surface in the supply resevoir is 20 kN/m². The other relevant data relating to the pump are as follows: Length of suction pipe = 5.0 m Crank Speed= 60 rpm Diameter of suction pipe = 10 cm Length of Stroke = 40 cm Diameter of cylinder = 20 cm Atmospheric presure = 100 kN/m²(abs) Calculate the pressure in the cylinder and force on the piston at the beginning of the suction stroke.
