MEASUREMENT OF GAUGE PRESSURE - SIMPLE MANOMETER

MEASUREMENT OF GAUGE PRESSURE - U-TUBE MANOMETER

Examples OF Variation OF Pressure, Barometer, Manometer

Statement - I: The temperature is measured by a device called manometer. Statement - II: The degree of hotness or coldness of a body is called temperature.

Consider a liquid at rest in a container which opens into atmosphere. At any point A at a depth h below the surface of the liquid, (i) the gauge pressure at point A is rho gh. (ii) the gauge pressure at point a is P _(a)+rhogh. (iii) The pressure at point A is rhogh. (iv) The pressure at point A is Pa + rho gh. The correct alternative is

A open ended mercury manometer is used to measure the pressure exerted by a trapped gas as shown in the figure. Initially manometer shows no difference in mercury level in both columns as shown in diagram. After sparking 'A' dissociates according to following reaction A(g)rarrB(g)+3C(g) If pressure of Gas "A" dissociates to 0.9 atm, then (Assume temperature to be constant and is 300 K)

The shot pressure is measured by
