Question

(a) Calculate the absolute pressure at the bottom of a freshwater lake at a depth of 27.5 $\mathrm{m}$ . Assume the density of the water is $1.00 \times 10^{3} \mathrm{kg} / \mathrm{m}^{3}$ and the air above is at a pressure of 101.3 $\mathrm{kPa}$ . (b) What force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 35.0 $\mathrm{cm}$ ?

Step 1

3 kPa $\rho$ = density of water = $1.00 \times 10^{3} \mathrm{kg} / \mathrm{m}^{3}$ $g$ = acceleration due to gravity = 9.81 m/s$^2$ $h$ = depth of the lake = 27.5 m Substitute the values into the formula: \[P_{\text {total }}=101.3 \mathrm{kPa}+(1.00 Show more…
