Question: Gasoline at a service station is stored in a cylindrical tank buried on its side, with the highest part of the tank 5 ft below the surface. The tank is 6 ft in diameter and 10 ft long. The density of gasoline is 45 lb/ft3. Assume that the filler cap of each automobile gas tank is 2 ft above the ground (Fig. 6.5.15).

1. How much work is done in emptying all the gasoline from this tank, initially full, into automobiles?
   
2. Recall that 1 hp is equivalent to 33,000 ft lb/min. For electrical conversions, l kW (1000 W) is the same 33 1.341 hp. The charge for use of electricity generated by a power company is typically about 7291/ kWh. Assume that, the electrical motor in the gas pump at this station is 30% efficient. How much does it cost to pump all the gasoline from this tank into automobiles?
