In physics, hydrostatic pressure is calculated by the following formula of p=p(rho) x h x g
Where p(rho) is the density of liquid the object is in, g is the gravitational field strength of earth and h is the depth of the object in the substance.
In this case density of water is 997kg/m3
997x2.9x9.81=283636.53 Pa
Absolute pressure is gauge pressure + atm pressure.
Hence,
283636.53 + 1.013x10^5 = 384936.53 pa
