Question

In a movie, James Bond evades the enemy by hiding underwater for may minutes by breathing through a long, thin reed. Assuming the maximum pressure difference his lungs can handed without crushing him is 11305N/m², what is the deepest he could go? The density of water is 1000kg/m³. Round to one decimal place and include units

Answer 1

P = gh

h = P / g

   = 11305 / (1000*9.8)

   = 1.1m
