Problem 6 It is required to pump gasoline from the gas tank of an automobile to the carburetor through a 1½-in.-diameter fuel line of 10-ft-long drawn tubing. The line has five 90° smooth bends with R 6. The gasoline is discharged through a 32-in.-diameter jet in the carburetor to an absolute pressure of 14 psi. The absolute pressure in the tank is 14.7 psi and the pump efficiency is 80%. Determine the power supplied to the pump if the automobile is consuming fuel at the rate of 28 in³/min. Consider the temperature of the gasoline to be 60°F. Answer: Welectric = 103 × 10-5 hp 2 ft Carburetor Pump 0.25 in line
