Consider the water tank below. It the tank is half full, nd the amount of work required to pump the water to the level of the top of the tank and out of the tank. (Use 1000 kg/m3 for the density of water and 9.8 m/s2 the acceleration due to gravity.) Be sure to set up the integral and nd the work needed. (Volume of a vertical cylinder: '0 = 7T'f'2 h) You must show all steps
