Approximately 30131

Please calculate according to Pascal's law. Calculate the hydrostatic pressure at a depth of 300m below sea level if the density of seawater is approximately 1025kg per m3. At what depth below the surface is the hydrostatic pressure 4.5 MPa?

Correct answer:

p1 =  3016.575 kPa
h2 =  447.5274 m

Step-by-step explanation:

h=300 m g=9.81 m/s2 ρ=1025 kg/m3  p=ρ g h=1025 9.81 300=3016575 Pa p1=p/1000=3016575/1000=3016.575 kPa
p2=4.5 1000000=4500000 Pa  p2 = ρ g h2  h2=ρ gp2=1025 9.814500000=447.5274 m
