Proble Que Revlo PHYS 222 Fluids at Rest Review Problems For each problem, list all information given with proper symbols, show formulas you intend to use and solve the problem. On the test, no credit will be given for answers without supporting calculations. 1. A submarine dives to a depth of 350 ft. a. What is the pressure on its hull due to the water? (use D = 64 lb/ft³ for seawater and put answer in pounds per square inch (psi)). Note: this is the gauge pressure on the submarine. b. What is the absolute pressure on the submarine? 2. A large ship's propeller is made of carbon steel with a weight density of 489 lb/ft³. If the propeller weighs 176 lb in air, what is its apparent weight when submerged in seawater? (D = 64 lb/ft³)
