What is the differential pressure measured by a manometer using mercury if the reference column rises 3.7 inches and the pressure column lowers 3.7 inches from the midpoint? mercury constant is 0.491

Question 15 Calculate the absolute pressure in Pascals at the bottom of a lake of depth 7.3 m. The lake is filled with fresh water with a density of 1000 kg/m and the atmospheric pressure is 102,829 Pa. Give your answer to the nearest whole number.

A Moving to another question will save this response. Question 11 Determine the absolute pressure at a point 2 m below the free surface of sea water of specific gravity 1.025. Take atmospheric pressure as 101325 Pa. O 121.110 kPa O 101.345 kPa O 20.211 kPa O 121.436 kPa
