A rectangular tank, open to the atmosphere, is filled with water to a depth of 2.5 m as shown. A U-tube manometer is connected to the tank at a location 0.7 m above the tank bottom. If the zero level of the Meriam blue manometer fluid is 0.2 m below the connection, determine the deflection l after the manometer is connected and all air has been removed from the connecting leg.

It floats vertically in water as shown below, with a depth k under water. Rust causes a small hole in the base and water leaks in slowly. Show that the tin floats in equilibrium again when the water has risen to fill a height h k/H+k, where H is the height of a water barometer.arrow_forwardHYDRAULICS A closed tank contains layers of fluids namely, air, oil(s=0.82), water, and molasses.
