A diver is 5.2m below the surface of water of density 1000Kgm-3. If the atmospheric pressure is 1.02 x 105pa. Calculate the pressure on the diver [g = 10ms-2]
6.20 x 104 pa
1.02 x 105 pa
1.54 x 105 pa
5.20 x 105 pa
คำอธิบาย
P = hpg + A.P
= 5.2 x 1000 x 10 + 1.02 x 105
= 1.54 x 105
= 5.2 x 1000 x 10 + 1.02 x 105
= 1.54 x 105
