A full water tank in the shape of a hemispherical bowl of radius 7 m. How much work is required to pump all the water to a height of 5 m above the tank? (The density of water is 1000 kg/m3). (Use symbolic notation and fractions where needed.) A full water tank in the shape of an inverted right circular cone is 20 m across the top and 10 m high. If the surface of the water in the tank is 2 m below the top of the tank, how much work is required to pump all the water over the top of the tank? (The density of water is 1000 kg/m3, use acceleration due to gravity g = 9.8 N/kg.) (Use symbolic notation and fractions where needed.) A swimming pool is in the shape of a rectangular parallelepiped (prism) a ft long, b ft wide, and c ft deep. If the pool is full of water, what is the force due to water pressure on one long side of the pool? Assume a = 35 ft, b = 25 ft, c = 2 ft. (Him: The weight density of water is 62.5 lb/ft3.) (Use decimal notation. Give an exact answer.)
