a) What is the gauge pressure of water at a depth of 38.7 m?
kPa
b) What is the actual pressure of water at this depth?
kPa
what formulas do i use and how do i do this?

drwls,
a) gauge pressure = (water density, kg/m^3)x(depth, meters)x(acceleration of gravity, m/s^2)
The answer will be in Pascals
b) add atmospheric pressure to the gauge pressure
