Answer #1

Maximum force that window can withstand, F =

Maximum gauge pressure that it can withstand, P = F/A

Gauge Pressure at depth h, = where is density of liquid. (For water = 1000kg/m3)

The submarine can go to a max depth of 954m safely.

A port hole (window) on a submarine has a radius of 30 cm. If the submarine is at a depth such that the water pressure is 4.04 x 10^5 Pa (about 30 m deep), and the submarine's air is at atmospheric pressure (use 1.01 x 10^5 Pa), what force must the surrounding bulkhead (submarine wall) exert on the port hole to keep it in place? 1.14 x 10^5 N toward the water 8.57 x 10^4 N toward the water 1.43...
