A rectangular tank that is 9 feet long, 5 feet wide and 6 feet deep is filled with a heavy liquid that weighs 110 pounds per cubic foot. In each part below, assume that the tank is initially full. Your answers must include the correct units. (You may enter of or lbft for ft-lb) (a) How much work is done pumping all of the liquid out over the top of the tank? (b) How much work is done pumping all of the liquid out of a spout 2 feet above the top of the tank? (c) How much work is done pumping two-thirds of the liquid out over the top of the tank? (d) How much work is done pumping two-thirds of the liquid out of a spout 2 feet above the top of the tank?

An aquarium 9 m long, 1 m wide, and 1 m deep is half-filled with water. Find the work needed to pump the water out of the aquarium. (Use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

A piston has an external pressure of 8.00 barbar. How much work has been done in joules if the cylinder goes from a volume of 0.180 litres to 0.650 litres. Express your answer with the appropriate units. W=

With the temperature held constant, the pressure of a gas in a cylinder with a movable piston is increased from 10 kPa to 90 kPa. The initial volume of the gas in the cylinder is 0.36 m squared. What is the final volume of the gas after the pressure is increased? Use the right formula to solve and get the correct answer.

how do we find the mass in this case? if we know that mass of single nuts is 0.0069kg W=m.gravety

A cylinder measuring 7.8 cm wide and 9.4 cm high is filled with gas and the piston pushed down with a steady force. piston cylinder gas ol. Ar Calculate the force on the piston if the pressure in the gas is measured to be 192. kPa. Write your answer in units of kilonewtons. Round your answer to 2 significant digits. O kN

Air flows at 210 m/s through the pipe. The temperature is 400 K and the absolute stagnation pressure is 280 kPa. Assume isentropic flow. For air R = 286.9 J/[kg - K] and k=1.40. (Figure 1) Figure 0.3 m

How much work (in J) must be done to inflate the balloon when the atmospheric pressure is 1.0 bar and the volume of the hot-air balloon is 16.1 m3 when inflated.

What mass of silver has a volume of 150 cm3?   A certain gas has a volume of 600 cm3.  What is its volume when the pressure is tripled?   Consider the gas in # 5 above.  What is its volume if the pressure is changed to one-third its original value?

A team in a Marshmellow challenge built a thrity inch tall structure in eighteen minutes. What is the average building speed of the team in inches per second? What will be the average speed in meters per second?
