Question
At the greatest depths that divers can work (and then only briefly), the pressure is 4.03 × 105 Pa. Noting that the density of saltwater is 1.025 × 103 kg/m3, what is the maximum depth for divers?
Answers
Look at the units you need:
(N/m^2) / (N/m^3) = m
you have the density of water in kg/m^3, so just change that to weight, and you have
4.03*10^5 Pa / (1.025*10^3 * 9.81 N/m^3) = ____ m
(N/m^2) / (N/m^3) = m
you have the density of water in kg/m^3, so just change that to weight, and you have
4.03*10^5 Pa / (1.025*10^3 * 9.81 N/m^3) = ____ m
