Diver and pressure

Determine what pressures is exposed diver without a suit at a depth of 15 meters, with a small space suit at a depth of 25 meters and a massive suit at a depth of 70 m in water.

Correct result:

p1 =  147.15 kPa
p2 =  245.25 kPa
p3 =  686.7 kPa

Solution:

r=1000 g=9.81 p1=r g 15/1000=1000 9.81 15/1000=294320=294320 kPa=147.15 kPa
p2=r g 25/1000=1000 9.81 25/1000=9814=9814 kPa=245.25 kPa
p3=r g 70/1000=1000 9.81 70/1000=686710=686710 kPa=686.7 kPa
