At the surface of a freshwater lake the pressure is 106 kPa.
(a) What is the pressure increase in going 34.9 m below the surface?in kPa
(b) What is the approximate pressure decrease in going 39 m above the surface? Air at 20
Homework Answers
a.)pressure increase=rho*g*h
=1000*9.81*34.9
=342.269 Kpa
b.)Decrease in pressure=1.2*9.81*39
=0.459 KPa ans

A submarine is 282 m horizontally from the shore of a freshwater lake and 110 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 209 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. (a) Draw a...
