determinr the liquid andabsolute pressure at a depth of 4min aswimmining poolgiven that the atmospheric pressure is approximately 101 kPa
What you are calling the "liquid pressure" must be the pressure due to liquid above, which is also called the gauge pressure. It equals
(density)*g*(depth)
= 1000 kg/m^3*9.8*4.0 m
= 3.92*10^4 Pa = 39.2 kPa
Add atmospheric pressure to that for the absolute pressure, 140.2 kPa.
