A tank is 8 m long, 4 m wide, 2 m high, and contains kerosene with density 820 kg/m^3 to a depth of 1.5 m. Find (a) the hydrostatic pressure on the bottom of the tank, (b) the hydrostatic force on the bottom, and (c) the hydrostatic force on one end of the tank. Draw a picture, label x_i and delta x. Then determine the Reimann Sum that defines the pressure. Evaluate the integral to determine the total work done.
