4. The volume of a 12 quart flexible container that is submerged to a depth of 170 ffw is _____.
5. A balloon filled with air has a volume of 20 cubic inches at 132 feet in the ocean. What is the volume of the balloon at 99 feet?
8. A diver with an 80 cu. ft., 3000 psi cylinder uses 1000 psi of air in 15 minutes at a constant depth of 75 feet in the ocean. The divers Surface Air Consumption rate in cubic feet per minute (Ft.3/min. or cfm) is __________.
9. An air consumption rate of 30 psi per minute using a 3,000 psi, 80 cu. ft. cylinder is equal to ____cubic feet per minute.
10. If a diver has a Surface Air Consumption rate of .8 cfm, with an 80 cu. ft. cylinder, the same tank filled to 3000 psi will last approximately ____minutes at a depth of 100 feet if the diver begins ascending with 500 psi of air in the tank.
11. If a tank contains 71.2 cubic feet of air at a pressure of 2475 psig, approximately _____feet of air remain at 2250 psig if the temperature remains constant.
12. Your calculations determine that it will take 320 pounds of lift to raise an object from the ocean floor. If the depth of the object is 99 fsw, how much air, measured in pounds per square inch, will be required from an 80 cubic foot (at 3000 psig)cylinder? (Disregard the fact that the deployed lift bag will be shallower than the object.)
A. 750 psi
B. 563 psi
C. 1500 psi
D. 734 psi

B.400
C. 450
D.520
