Answer:
64,717.36 Joule is the total amount of work needed to pump the gasoline out of the tank.
Step-by-step explanation:
Volume of cylinder = V
Radius of cylinder = r = 0.5 m
Height of the cylinder = 5 m
Volume of cylinder =
Mass of gasoline = m
Density of gasoline = d =
Work done to pump the gasoline out of the tank W
Acceleration due to gravity = g
The center of gravity of fuel in fully filled tank will be centre so, the value of h = 2 m + 0.5 m = 2.5 m
64,717.36 Joule is the total amount of work needed to pump the gasoline out of the tank.
