In an inverted U-tube differential manometer, how is the specific gravity of fluid used in manometer relative to the fluid flowing in the pipes?

Which of the following statements are correct.

1) Manometers works by balancing the column of fluid by the same or another column of the fluid.

2) Manometers works by balancing the fluid column by the spring or dead weight.

3) Mechanical gauges works by balancing the fluid column by spring or dead is eight.

4) Mechanical gauge works by balancing the column of fluid by same or another column of fluid.

Which of the following is correct?

An inclined manometer can measure the pressure difference of 200 Pa. The inclined manometer has a least count of 4mm using mercury. The sensitivity of manometer is

The figure shows the cross-section of an oil pipe with a manometer attached. On the right side of the manometer the manometer fluid is in contact with oil, and on the left side the manometer is open to the atmosphere. The oil has a specific gravity of 0.85 and the manometer fluid has a specific gravity of 1.5. What is the gage pressure at the center of the pipe if h_m is 10 cm and h₀ is 5 cm?
