Question

Crater Lake in Oregon is the deepest lake in the United States, with a maximum depth of 655 m. The density of freshwater is 1.00 ✕ 103 kg/m3.

(a) If the air pressure above the lake, which has a surface altitude of 1800 m, is 8.00 ✕ 104 Pa, what is the absolute pressure at the bottom of the lake?

(b) What is the force of the lake's water on each window of a submarine near the lake bottom if each of its circular windows has an area of 191 cm2? (Enter the magnitude.)

Answer 1

a) P = Po tegh = 8x10" + 163x9.80655 >> 8x16"+ 641.9410" » 649.9x104 Pa F = PA : 649.96101191xlo 4 m² - 124,130.9N Scanned with CamScanner
