1mof h2o 76/10.3 = 7.4.

10.3m of H2O = 76Cm of hg.
1 m of H2O = 7.378.
So, the answer is B.
1 m of H2O = 7.378.
So, the answer is B.

Here it is 7.4m of Vaccum pressure and 2.5m of absolute pressure for water.

The pressure at summit point will be less than the atmospheric pressure . Theoretically, the pressure at summit may be reduced to 10.3 m of water but in actual practice, this pressure is only 7.6 m of water or 10.3-7.6= 2.7m of water absolute. if the pressure at summit become less than 2.1m of water absolute, the dissolved air and other gases would come out from water and collect at the summit.the flow of water will be obstructed.

It should be less than 7.8 because if it goes above 7.8 dissolved gases in the liquid will come out and accumulated at a summit and will stop flow of water.

It should be 7.8m water.

According to me, 2.7 is the correct answer.
