What is a manometer?

A manometer reads the pressure of a gas in an encloure as shown in fig. when some of the gas is removed by the pump, the manometer reads as in fig. the liquid used in mano-meters is mercury and the atmospheric pressure is 76 cm of mercury. (i) Given the absolute and gauge pressure of the gas in the two cases (in units of cm. of mercury). (ii) How would the levels change in case(b) if 13.6cm of water are poured into the right limb of manometer? (Ignore the change in volume of the gas).

What is the difference between barometer and manometer?

What are the two longest wavelength lines (in manometers) in the Lyman series of hydrogen spectrum ?

Pressure of a gas enclosed in a container can be measured using a manometer.

A manometer has a vertical arm of cross sectional area 9A and an inclined arm having area of cross section A. The density of the manometer liquid has a specific gravity of 0.74. the scale attached to the inclined arm can read up to +-0.5mm . It is desired that the manometer shall record pressure difference (P_(1)-P_(2)) up to an accuracy of +- 0.09 mm of water. To acheive this, what should be the inclination angle theta of the inclined arm.

When cut stumps of a plant is fitted with a manometer, the level of mercury rises due to the accumulation of

A 82.1 L container connected with manometer contains mixture of CS_(2) and H_(2)S gases and added with required amount of oxygen to form to CO_(2),SO_(2) and H_(2)O(g) at 227^(@)C . Final conditions of manometer is shown.

A container A is having some fluid of density theta_(0) . If is connected with a U tbe manometer shown in figure. Find the pressure of the container in both the cases given in figure.
