A vertical dam has a semicircular gate as shown in the figure. The total depth d of the figure is 42 m, the height h of air above the water level is 6 m, and the width w of the gate is 8 m. Find the hydrostatic force against the gate. (Round your answer to the nearest whole number. Use 9.8 m/s2 for the acceleration due to gravity. Recall that the weight density of water is 1000 kg/m3.)

A bubble having a diameter of 82 cm is re- leased from a depth of 5.1 m from the bottom of a swimming pool. The temperature of the water at the surface is 20◦C, whereas it is 15◦C at the bottom. What will the diameter of the bubble be when it reaches the surface? The acceleration of gravity is 9.8 m/s2 and the density of water is 1000 kg/m3. Answer in units of cm.

QI: An open tank as shown in figure (1) has a vertical partition and on one side contains gasoline with a density p= 700 kg m' at a depth of 4 m. A rectangular gate that is 4m high and 2m wide and hinged at one end is located in the partition. Water is slowly added to the empty side of the tank. At what depth, h, will the gate start to open?
