Question

an inverted right circular gasoline tank of radius 2 ft and height 8ft is buried in the ground so that the circular top is 1 f below the ground (parallel to the ground). Howw much work (in ft-lbs) is required to pump the gasoline occupying the top foot of the tank to aheight 2ft above the ground if the tank id full. (ignore the water the ends in the hose from the pumping process aftertop foot is done being pumped out - assume it's negligible ) the force-density of gasoline is pg=45 lb/ft3

Answer #1

Suppose we have a rectangular tank buried upright so that the
top is 7ft underground. The tank is 11ft deep, 3ft wide, and 5ft
long. It is filled to the 3 foot mark with gasoline, which has a
density of 46.75lbs/ft3. Set up an integral which represents the
work required to pump all of the gasoline into a container that
sits 2ft above the surface.

A tank in the shape of an inverted right circular cone has
height 88 meters and radius 1616 meters. It is filled with 22
meters of hot chocolate.
Find the work required to empty the tank by pumping the hot
chocolate over the top of the tank. Note: the density of hot
chocolate is δ=1450kg/m3

A tank in the shape of an inverted right circular cone has
height 9 meters and radius 13 meters. It is filled with 3 meters of
hot chocolate.
Find the work required to empty the tank by pumping the hot
chocolate over the top of the tank. Note: the density of hot
chocolate is δ=1480kg/m^3

A tank in the shape of an inverted right circular cone has
height 6 meters and radius 2 meters. It is filled with 5 meters of
hot chocolate. Find the work required to empty the tank by pumping
the hot chocolate over the top of the tank. The density of hot
chocolate is \delta = 1090kg/m^3 Your answer must include the
correct units.

A tank in the shape of an inverted right circular cone has
height 7 meters and radius 3 meters. It is filled with 6 meters of
hot chocolate. Find the work required to empty the tank by pumping
the hot chocolate over the top of the tank. The density of hot
chocolate is δ=1080 kg/m^3. Your answer must include the correct
units.

NOTE: 112174.092J is incorrect?

A tank in shape of an inverted right circular cone has height 10
m and radius 10 m. it is filled with 7 m of hot chocolate. Find the
work required to empty the tank by bumping the hot chocolate over
the top. density of chocolate equal 1510kg/m^3
