Question

A scuba driver with a local sheriffs office has been assigned the task of retrieving a sunken car in the Red river. The car is believed to have human remains inside. The scuba driver descends to a depth that's 60 feet below the surface of the river and breathes out a stream of bubbles. What is the total gas pressure of these bubbles at the moment they are release? What is the gas pressure in the bubbles when they reach the surface of the river?

Answer 1

We are asked to determine in this problem to determine the pressure that is experienced underwater. Pressure underwater is the sum of atmospheric pressure and the pressure brought about by the change in height, that is Punder = P atm + density salt water * g* height (66ft) . P atm or the pressure at the surface is equal to 1 atm.
