A utube manometer contains mercury of density 13,600 kg/m3. One end of the manometer is open to the atmosphere and the other end is connected to a low pressure natural gas line. A height difference of 11.8 cm results between the levels of the two liquid columns, with the side connected to the game line being lower. The atmospheric pressure is 99,200 Pa.
1. What is the absolute pressure inside the gas line in pascals?
2. What is the gauge pressure in psi units?
would I apply bernailli's equation here? i know the density is higher in this so does that mean the pressure will be higher? i'm confused...
