If the water in a lake is everywhere at rest, what is the pressure as a function of distance from the surface? The air above the surface of the water is at standard sea-level atmospheric conditions. How far down must one go before the pressure is 1 atm greater than the pressure at the surface?

Respuesta :

Answer:

Answer:

101325 + 10055.25h

//

h = 10.1 m

Explanation:

the pressure at sea level =  1 atm = 101325 Pa

density of sea water = 1025 kg/ m^(3)

pressure due to fluid height = pgh

Absolute pressure = 101325 + 1025*9.81*h

                               = 101325 + 10055.25h

where h= 0 at sea level at increases downwards

//

101325 = 1025* 9.81* h

h = 10.1 m
