A 75 mm-Ø orifice is on the vertical side of a closed tank. The tank rests on a flat ground and the orifice is 0.5 m above the ground. Filled with four fluids with air on the topmost portion that is under a pressure of 15 KPa, and the rest of specific gravities of 0.80, 1.0, and 1.50, respectively, the jet hits the ground at a horizontal distance of 3.75 m. If the liquids have the same thickness, and the power lost in the system is 233 watts, determine the following: (a) The initial discharge in L/s if C=0.63. (b) The thickness of each liquid in m. (c) The coefficient of contraction.
