What will be the length of mercury column in a barometer tube when the atmospheric pressure is x cm of mercury and the tube is inclined at an angle `phi` with the vertical direction ?

What will be the length of mercury column in a barometer tube when the atmosperic pressure is 75 cm of mercury and the tube is inclined at an angle of 60^@ with the horizontal direction?

What will be the length of mercury column in a barometer tube, when the atmospheric pressure is 76 cm of mercury and the tube is inclined at an angle of 30 ^(@) with the horizontal direction ?

Explain how is the height of mercury column in the tube of a simple barometer, a measure of the atmospheric pressure.

Suppose the pressure at the surface of mercury in as barometer tube is P_1 and the pressure at the surface of mercury in the cup is P_2 .

Suppose the pressure at the surface of mercury in as barometer tube is P_1 and the pressure at the surface of mercury in the cup is P_2 .

Suppose the pressure at the surface of mercury in as barometer tube is P_1 and the pressure at the surface of mercury in the cup is P_2 .

Calculate the length of mercury column in a barometer tube which is inclined at an angle of 45^(@) with horizontal direction if the atmospheric pressure is 75 cm of mercury.

If the length of the mercury column in a mercury barometer is 76 cm, what is the equivalent height of the water column ?
