gas valve not working

>The gas valve of the gas outlet is opened to get a supply of biogas. Once the production of biogas begins, a continuous supply of gas can be ensured by regular removal of spent slurry and introduction of fresh slurr..

>The spent slurry is manually removed from the overflow tank and used as manure for plants The gas valve connected to a system of pipelines is opened when a supply of biogas is required To obtain a continuous supply of biogas, a functioning plant can be fed continuously with the..

The various forms of biomass are mixed with an equal quantity of water in the mixing tank. This forms the slurry. The slurry is fed into the digester through the inlet chamber. When the digester is partially filled with the slurry, the introduction of slurry is stopped and the plant is left..

. So, the heat supplied is assumed to increase only the temperature. However, the coefficient of expansion is very large in case of gases. Thus, if a gas is heated the heat energy is required, not only to increase the temperature of the gas but also to do mechanical work..

) holds good at all pressures and temperatures. This is an idealized model. It works best at very low pressures and high temperatures, when the gas molecules are far apart and in rapid motion. It is reasonably good (within a few per cent) at moderate pressures (such as a few atm..

V) is, by chance, very close to level E 2 in neon (= 20.66 eV). So, during collisions between helium and neon atoms, the excitation energy of the helium can be readily transferred to the neon. In this way level E 2 can become more highly populated than level E 1 . This population inversion is maint..

Work is another mode of transference of energy. Work is said to be done if the point of application of force undergoes displacement in the direction of the force. If the system loses energy, we say that the work is done by the system. Alternatively, if the system gain..

v are measured in J K - 1 mol - 1 . C p is greater than C v . If a gas is heated at constant volume, the gas does no work against external pressure. In this case, the whole of the heat energy supplied to the gas is spent in raising the temperature o..

Every month, Mary works 34 hours in a pizza corner, 48 hours in a gas station, and 68 hours as a tutor. About how many hours does Mary spend working every month? => 100 hours or 130 hours or 180 hours or 150 hours..
