Question

A scuba diver is in fresh water has an air tank with a volume of 0.0100 m³. The air in the tank is initially at a pressure of 1.00 × 10⁷ Pa. Assume that the diver breathes 0.500 L/s of air. Density of fresh water is 1.00 × 10³ kg/m³.

 

How long will the tank last at depths of 4.10 m?

 

Answer 1

$t=\frac Vv\frac{p}{\rho gh}=40~s.$
