Fluid Mechanics: Solved Manometer Problem

MEC516/BME516 Fluid Mechanics: A solved manometer problem from a previous Fluid Mechanics midterm exam. The problem involves calculating a pressure difference using fluid levels in a manometer. The pressure difference in the air-filled section is neglected because the density of gases is two orders of magnitude less than liquids.

why the gamma of the water using 998 and not 1000?

Denisity of water at 20C is 998 kg/m^3. But the difference is only 0.1% so don't get hung up on this issue.
