pressure variation
pressure variation
(OP)
we had a doubt about the given data as suction pressure is 59 meteres above the mean sea level..? if we calculate this with p=qgh it is not matching..and one thing is as the altitutde increses gradually the pressure has to decrease but if we apply the same formula how will it match ...?





RE: pressure variation
P = 29.92 - 0.001H where P = atmospheric pressure in inches of Hg, and H = height of the area from MSL in feet.
So for 59 meters it is 29.92 - (0.001 x 59 x 3.28)= 29.72 inches of Hg. (or 755 mm of Hg)
Check this with your barometer.

RE: pressure variation
14.69psi*144 sqin/sqft/ 62.4 lbs/cu.ft= 33.9 feet of water or 406.8 inches of water. Therefore you have
27.69 inches of water per psi.
You can do the conversion!!!
