5.3
The surface of water at a certain point in the swimming pool has a temperature
of 27 °C at the atmospheric pressure of 101,325 kPa. The temperature at the
bottom of the swimming pool is 10 °C. An air bubble with a diameter of 10 mm
is let loose from the bottom. Calculate the depth of the swimming pool if the
bubble has a diameter of 20 mm when it reaches the surface.
HINT: Calculate the difference in pressure at the top and the bottom, and then
use the relevant formula to determine the depth.
