Question

When the level of mercury in the attached branch of manometer that 

means the gas pressure in the reservoir is

Answer 1

Answer:manometer are defined as devices used to measure the pressure at in a point in a fluid. These are also used a measure the difference in pressure between two points in s pipes or in two different pipes. Principle of manometers:- manometer are based on the principle of balancing the column of fluid by the same or another column of the fluid. manometer are defined as devices used to measure the pressure at in a point in a fluid.

It consists of a glass tube bent in Ushape. One end of this tube is connected to a point at which pressure is to be measured and the other end remains open to the atmosphere. The tube generally contains a liquid (called manometric liquid or balancing liquid) whose specific gravity is greater than the specific gravity of the liquid whose pressure is to be measured.
