Chapter 3 Review

  1. Convert a gauge pressure of 24 ft to pounds per square inch gauge.
  2. A head of 195 feet is equal to what pressure in pounds per square inch gauge?
  3. A pressure of 95 psig is equivalent to how many feet of water?
  4. What would the static pressure be on a pressure gauge at the bottom of a 30 foot wide water tower that contained 150 feet of water?
  5. Calculate the pressures at points A and B in this diagram of water storage tanks.
  6. The pressure on a surface is 27 psig. If the surface area is 144 in2, what is the force (in pounds) exerted on that surface?
  7. If there is a pressure of 125 psig pressing against a surface 8 ft by 10 ft, what is the force exerted against the surface?
  8. In the hydraulic jack diagram below, the operating piston has a surface area of 10 in2 and a lifting piston has a surface area of 150 in2. A force of 250 lbs is applied to the operating piston. What pressure is created within the hydraulic system of the jack and what is the resulting force exerted on the lifting piston?
