Physics - Submerged Cylinder
posted by Phil .
A cylindrical diving bell 5 m in diameter and 10 m tall with an open bottom is submerged to a depth of 150 m in the ocean. The temperature of the air at the surface is 20 degrees Celsius, and the air temp 150 m down is 2 degrees Celsius. The density of seawater is 1025 kg/m^3. How high does the sea water rise in the bell when the bell is submerged?
(1) Find volume of cylinder
(2) Find volume of air in cylinder when submerged
(3) Vcyl - Vair = Vwater
I think you use the formula P=Po + pgh to find the height of the air pocket, but I'm not sure what values to use for P, Po, and p. Please help.
theta=contact angle (for water=0)
