—-A certain part of an aircraft engine has a volume of 1.5 ft3.

(a) Find the weight of the piece when it is made of silver.

(b) If the same piece is made of aluminum, what is its weight?

Determine how much weight is saved by using aluminum instead of silver.

—–The water in the plumbing in a house is at a gauge pressure of 160,000 Pa. What force does this cause on the top of the tank inside a water heater if the area of the top is 0.9 m2? (Ignore atmospheric pressure.)

—–A storage tank 32 m high is filled with gasoline. (Assume the tank is open and exposed to the atmosphere at the top.)

(a) Find the gauge pressure at the bottom of the tank.

(b) Calculate the magnitude of the force produced by the fluid that acts on a square access hatch at the bottom of the tank that measures 0.7 m by 0.7 m.

—–A modern-day zeppelin holds 9,520 m3 of helium. Compute its maximum payload at sea level. (Assume the helium and air to be at 0¬įC and 1 atm.)

—–A juniper-wood plank measuring 0.41 ft by 1 ft by 17 ft is totally submerged in water. (a) What is its weight?
