A diving bell is a 4.1 m -tall cylinder closed at the upper end but open at the lower end. The temperature of the air in the bell is 20 ∘C. The bell is lowered into the ocean until its lower end is 100 m deep. The temperature at that depth is 10∘C.
Part A) How high does the water rise in the bell after enough time has passed for the air to reach thermal equilibrium?
Part B) A compressed-air hose from the surface is used to expel all the water from the bell. What minimum air pressure is needed to do this?

The thin-walled, 1-m-diameter tank of Fig. P2.144 is closed at one end and has a mass of 90 kg. The open end of the tank is lowered into the water and held in the position shown by a steel block having a density of 7840 kg/m3. Assume that the air that is trapped in the tank is compressed at a constant temperature. Determine: (a) the reading on the pressure gage at the top of the tank, and (b) the volume...

HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
