5Atm5Atm

Explanation:

The pressure exerted by a static fluid depends only upon height hh of the fluid column, the density rhoρ of the fluid, and acceleration due to gravity gg.

The pressure in a static fluid is given by the expression

P_"static fluid" = ρgh
my computer

  1. At the surface the pressure is due to atmosphere.
  2. At depth h pressure is sum of pressure due to air and pressure due to water column of depth h
    P_h=Air+"pressure due to water of depth "h
    Inserting given values we obtain
    3Atm=1Atm+"pressure due to water of depth "h
    =>"pressure due to water of depth "h=3-1=2Atm
  3. :."pressure due to water of depth "2h=2xx2=4Atm
    Now P_(2h)=Air+"pressure due to water of depth "2h
    Inserting calculated value we obtain
    P_(2h)=1+4=5Atm
