A manometer reads the pressure of a gasin an enclosure asshown in Fig. 10.25 (a) When a pump removes some of the gas, the manometer reads as in Fig. 10.25 (b) The liquid used in the manometersis mercury and the atmospheric pressure is 76 cm of mercury.Give the absolute and gauge pressure of the gas in the enclosure for cases (a) and (b), in units of cm of mercury.:

A manometer reads the pressure of a gasin an enclosure asshown in Fig. 10.25 (a) When a pump removes some of the gas, the manometer reads as in Fig. 10.25 (b) The liquid used in the manometersis mercury and the atmospheric pressure is 76 cm of mercury.How would the levels change in case (b) if 13.6 cm of water (immiscible with mercury) are poured into the right limb of the manometer ? (Ignore the small change in the volume of the gas).:

What is the absolute and gauge pressure of the gas above the liquid surface in the tank shown in the following figure? Density of oil = 820 kg m^-3 , density of mercury = 13.6 xx 10^3 kg m^-3 , 1 atmosphere pressure = 1.01 xx 10^5 pa .

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 2A(g)rarr 3B(g)+2C(g) If pressure of Gas "A" dissociates to 0.8 atm, then (Assume temperature to be constant and is 300 K)
