Water flows freely from the reservoir though a 57.95 mm diameter pipe at the rate of 6.1 L/s. If the head lost in the system is 11.32 J/N, solve for the elevation of the water surface in the reservoir. Round your answer to 3 decimal places.
The tank shown in figure is of a depth d = 48.8 cm and width w =24.4 cm accelerated by ax = 3.43m/sec2 to the right, find the allowable water height (h) to avoid spill of water during acceleration
Water flows from a reservoir into a rigid horizontal pipe whose intake is 52m below the surface elevation of the reservoir. The pipe discharges through a valve into the atmosphere and is 0.6m in diameter and 1.5km long. Assuming a rigid water column calculate the pressure rise at the valve if it is closed in 4.5 seconds. Assume a friction factor of 0.008. If the valve is re-opened at some later time, calculate the time taken for the flow to accelerate to 65% of its steady state value. Answers (120.63m, 8.3s)
The water system in a suburban area consists of an old 200mm pipeline 760m long which conveys water from a pump to a reservoir whose water surface is 107m higher than the pump. Water is pumped at the rate of 0.07 m3/s. Determine the horsepower saved by replacing the old pipe with a new 250mm pipe. Assume the value of f as equal to 0.022 and 0.033, respectively, for the old and new pipes. Neglect losses of head except friction head show the diagram and complete solution. Need ASAP. Thank you
