Fig. 1.1 illustrates sea water moving down a channel and into a tank without any splashing. The rate of flow is 800 kg/min. The tank has a length of 3.10 m and a width of 1.20 m. The density of the sea water is 1020 kg/m$^3$. Fig. 1.1 (not to scale) labels the flowing sea water, channel and tank, and shows dimensions 3.10 m and 1.20 m.
(a)[3]
Calculate the depth of water in the tank after 1.00 minute, and give your answer to three significant figures.
(b)[3]
Calculate the reduction in gravitational potential energy of the water each second.
(c)[3]
Calculate the pressure at the bottom of the tank that is due to the water.
