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

Answer 1

Answer:1.152 m

Explanation:

Given

Maximum Pressure difference his lungs can bear is 11305 $N/m^2$

We know that Pressure difference at the height h below liquid is given by

$\Delta P=\rho \times g\times h$

Given

$\Delta P=11305 N/m^2$

$\rho$ =density of water=1000$kg/m^3$

acceleration due to gravity$\left ( g\right )=9.8m/s^2$

11305=$\rho \times g\times h$

11305=$1000\times 9.81\times h$

$h=\frac{11305}{9.81\times 1000}=1.152 m$
