Question

Thirty feet of water exert a pressure of 1 atm. Calculate the pressure (in kPa) exerted on a diver at a depth of 50 feet on a standard day.

Answer 1

the gage pressure (pressure above one atm) would be
(5/3)*1 atm
but 1 atm = 101325 Pascals=101.325kPa

so
(5/3)(101) kPA

if you want absolute pressure add 1 atm or 101 kPa to that

Answer 2

So why is it 5/3 not 3/5 because P1V1=P2V2 right?
