Question

what is the pressure at water level, when density of water p= 1.000 x 10 ^3 kg/m^3 atmospheric pressure at sea level= 1.013 x 10 ^5 pa ?

Answer 1

1.013 x 10⁵ pa

Step-by-step explanation:

p₀ = Atmospheric pressure = 1.013×10⁵ Pa

ρ = Density of water = 1×10³ kg/m³

g = Acceleration due to gravity = 9.81 m/s²

h = Height at which the pressure is to be found = 0 at water level

Absolute pressure is given by

p = p₀ + ρgh

⇒p = 1.013×10⁵ + 1×10³×9.81×0

⇒p = 1.013×10⁵ Pa

∴ Absolute pressure at the water level is 1.013×10⁵ Pa.
