Question

Calculate the pressure in N/m^2 experienced by a diver at a point 15m below th
water surface in a lake (given that latm=1.01x105Pa, density of water=1000kg/m^3
g=10m/s^2).
​

Answer 1

Answer:

P = P° + hdg

= 1.01 × 10^5 + 15×1000×10

= 1.01 × 10^5 + 1.5 × 10^5

=10^5 ( 1.01 + 1.5)

=10^5 × 2.51 pascal Or N/m^²
