A rectangular gate 1.4 m in base and 1.8 m high is placed on the face of the water reservoir, as shown in the figure. Its upper portion is hinged and the base is attached to a cylindrical buoy whose weight is 20 kg. The external diameter of the buoy is 2 m and the weight of the gate is 50 kg. The mechanism is such that the buoy will open the gate if water surface will rise higher than 4 m. What is the height of the buoy below the water surface?

Solve for the absolute pressure of oil at 10-m below its surface if the barometric reading is equivalent to 752 mmHg. Oil specific gravity = 0.75. An open tank has 5.8-m depth of water, on top of that layer is 3.2-m depth of kerosene which has a unit weight of 8 kN/m³. Solve for the pressure at the bottom of the tank. (Draw the figure).
If a steel rectangular gate (see Figure 1) of 1.0m wide by 1.66 m high, is located in the wall of a reservoir. It is hinged at the top and acts as a relief valve such that when the water level reaches 1.35m above the top of the gate the gate starts to open allowing water to leave the reservoir. If the gate is inclined at 66º to the horizontal, and the density of steel is 7600 kg/m3, determine the thickness of the gate.

A conical tank is inclined with an angle of 60°. A hole with radius 2-in was opened at the bottom. If initially the tank is full to a height of 9 ft, how long will the tank drain? Consider a coefficient of contraction, 0.6.
A trough is 12m long, 5m wide, and 3m deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 3m, and base, on top, of length 5m). The trough is full of water (density 1000kg/m³ and g = 9.8m/s² is the acceleration due to gravity). a) Find the amount of work in joules required to empty the trough by pumping the water over the top. b) Find the amount of work in joules required to empty the trough by pumping the water out of a spout 4m high.
