`P_1 = 0, P_2` = atmospheric pressure

B

`P_1` = atmospheric pressure, `P_0 = 0`

C

`P_1 = P_2` = atmospheric pressure

D

`P_1 = P_2 = 0`

Text Solution

Measuring Pressure By Mercury Barometer

A barometer is constructed with its tube having radius 1.0 mm. Assume that the surface of mercury in the tube is spherical in shape. If the atmospheric pressure is equal to 76 cm of mercury, what will be the height raised in the barometer tube? The contact angle of mercury with glass 135^@ and surface tension of mercury =0.465Nm^-1 . Density of mercury =13600kgm^-3 .

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?

A barometer tube contains a mixture of air and saturated water vopour in the space above the mercury column. It reads 70cm when the actual atmospheric pressure is 76cm of mercury. The saturation vapour pressure at roon tempature is1.0 cm of mercury, The tube is now lowered in the reservoir till the space above the mercury cloumn is reduced to half its origina volume. Find the reading of the barometer. Assume that the temperature remains constant.
