Question

PLEASE DO NOT OMIT STEPS, EXPLAIN IT DETAILED MIND PLEASE, ALSO WRITE BIG SO THAT I CAN LOOK AT IT AS I CAN CONFUSE THANK YOU VERY MUCH!

APART OF RESOLVING IT IF YOU CAN SAY ME BECAUSE WHEN DOING THE JOURNEY OF THE PRESSURE OF THE DUCT TOWARDS THE ATMOSPHERIC PRESSURE, IS THE PRESSURE OF THE AIR DESPRECIATED?

When measuring small temperature differences with a manometer, one of its branches is inclined, to improve the accuracy of the measurement. (The pressure difference is still proportional to the vertical distance and not to the length of the tube occupied by the liquid) The air pressure in a circular duct is measured using a pressure gauge, whose open branch is inclined at 35º with the horizontal, as is shown in figure P1-110. The density of the liquid in the manometer is 0.81 kg / L and the vertical distance between the fluid levels in the two branches of the manometer is 8cm. Calculate the manometric pressure of the air in the pipeline, and the length of the column of the liquid in the inclined branch, above the level of the liquid in the vertical branch
