Question

find the pressure at a depth of 10m in water if the atmospheric pressure is hundred k pa

Answer 1

Pressure at depth d = atmospheric pressure + depth×density of water×acceleration due to gravity
=100 + 10×1000×10
=100+100000
=100100 Nm

Answer 2

pressure =hdg (density of water=1000kg/m3
and g=10m/s2
=10*1000*10=100000=100kPa
total pressure =100+100=200kPa
