Question

A cylindrical tube with length l=0.141 m is sealed at one end. On the surface it is filled with air at a pressure of 1 atm=1.01x105 Pa. It is submerged

in seawater to a depth of h=10.4 m. The density of the seawater is p=1029 kg/m3. The air and water are at a temperature T=18.9 ° C.As the tube submerges water enters the tube. What is the length of air in the tube at a depth h=10.4 m?How far below the surface is the tube if water has risen 1.00 cm up the tube?
