1. The rectangular gate measures 8 m by 4 m (l = 8 m) and is pin-connected at point B as shown in Fig. 1. If the surface on which the gate rests at A is frictionless and if the water surface is 5 mm above point B, what is the reaction at A?

2. Determine the hydrostatic force F on the triangular gate, which is hinged at the bottom edge and held by the reaction RT at the upper corner (refer Fig. 2). Express F in terms of γ, h, and W. Also determine the ratio RT/F. 3. Water flows steadily down the inclined pipe as indicated in Fig. 3. Determine the difference in pressure p 1-p2 ,

4. A diving bell is idealized as a cylinder of length L closed at one end, as shown in Fig. 4. At sea level it is full of air. As it sinks the air is compressed and the water rises into the bell to a height h. Derive a relation between h and the depth H if the compression of air is assumed isothermal. Simplify for L...
