1.Water flows from a large open tank through a sharp edged entrance and into a galvanized iron pipe of a length 1.5 miles and diameter of 4 inches. The water exits the pipe as a free jet at a distance (h) below the free surface of the tank. Plot of Log-Log grah of the flowrate, as a funciton of h for h in between .2 ft and 20 ft.
2.Three new cast iron pipes, having diameters of 24, 21 and 18 in respectively, each 450-ft long, are connected in series. The 24-in pipe leads from a reservoir (flush entrance), and the 18-in pipe discharges into the air at a point 15 ft lower than the reservoir water surface level. Assuming all changes in section to be abrupt, find the rate of discharge of water at 60 degrees Fahreneit.
