My calculation was $$Delta P = rhogh$$
$$\Delta P = (1.05\times10^{3}) \times 9.8 \times 6$$
$$DeltaP = 6.17\times10^{4} Pascals$$

Why are they dividing each side of the equation my the atmospheric pressure?

anonymous · Answer

He has changed the units from "pascals" to "atm" .

followthefez · Answer

anonymous · Answer

No ,you may leave it in pascals.
But still confirm it from someone else also ,just in case i am wrong.
