diver descends 100 m to a sunken ship.  A container is found with a pressure gage reading 100 kPa (gage). Atmospheric pressure above the water is 1.01 bar. What is the absolute pressure of the gas in the container? (The specific gravity of seawater is 1.2 times that of pure water.)

Please solve it correctly ( Don't copy paste any wrong solution ) I have confusion in taking value of density , Whether its air or water.

An aquarium 7ft long, 3ft wide, and 5ft deep is full of water. The gravitational acceleration is g = 32ft/s². The density of water is p = 1.95slug/ft³. Answer the following questions. 1. Find the hydrostatic pressure on the bottom of the aquarium. Answer (in pounds per sq. foot): 2. Find the hydrostatic force on the bottom of the aquarium. Answer (in pounds): 3. Find the hydrostatic force on one end of the aquarium. Answer (in pounds): FI

Please use a paper sheet to solve.

A vacuum gage connected to a chamber reads 29.61 kPa at a location where the barometric pressure is 99.78 kPa. Compute the absolute pressure in the chamber in inches of mercury.
