Question

(a) Calculate the absolute pressure at an ocean depth of 1 $000 \mathrm{~m}$. Assume the density of seawater is $1024 \mathrm{~kg} / \mathrm{m}^{3}$ and that the air above exerts a pressure of $101.3 \mathrm{kPa}$. (b) At this depth, what force must the frame around a circular submarine porthole having a diameter of $30.0 \mathrm{~cm}$ exert to counterbalance the force exerted by the water?

Step 1

3 \text{ kPa} = 101300 \text{ Pa}\] \[\rho = 1024 \text{ kg/m}^3\] \[g = 9.8 \text{ m/s}^2\] \[h = 1000 \text{ m}\] Plugging in the values: \[P_{\text{absolute}} = 101300 + 1024 \times 9.8 \times 1000\] \[P_{\text{absolute}} = 101300 + Show more…
