Two reservoirs are connected by two parallel pipes of equal length and of diameters 20 cm and 10 cm, as shown in the figure (not drawn to scale). When the difference in the water levels of the reservoirs is 5 m, the ratio of discharge in the larger diameter pipe to the discharge in the smaller diameter pipe is (Round off to two decimal places) (Consider only loss due to friction and neglect all other losses. Assume the friction factor to be the same for both the pipes) ! Reservoir 5 m 20 cm 10 cm ļ Reservoir

A dam supplies to a suburban area using a 0.21m diameter pipeline that is 800m long. For the water to reach the intended reservoir, a pump is needed to raise the flow to a point 125m above the pump. If the flow within the pipe is 0.11 m3/s, determine the savings in horsepower if the engineers decided to replace the old pipe (f = 0.034 with a new 0.29m diameter pipe with f = 0.024.
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.
