WEBThe daily consumption of coal is calculated using the information that each day there is × 10 14 J of heat transfer from coal. In the combustion process, we have C + O 2 → CO 2. So every 12 kg of coal puts 12 kg + 16 kg + 16 kg = 44 kg of CO 2 into the atmosphere. Solution for Part 3. The daily coal consumption is
WEBNov 19, 2020 · For an irreversible adiabatic process entropy is generated within the system resulting in an increase in the entropy of the system only. An example of an irreversible adiabatic process is the rapid expansion or compression of a gas by a piston in an insulated cylinder such that the gas is not in internal equilibrium during the process.
WEBAug 8, 2019 · Coalescence is a merge of two or more droplets into a single droplet, with the rupture of the surface film of each droplet, forming a new and larger droplet, independent of the other droplets. It is an irreversible process, different from flocculation and sedimentation, which also allow two or more droplets to merge into a single droplet.

WEBFigure Quasistatic and nonquasistatic processes between states A and B of a gas. In a quasistatic process, the path of the process between A and B can be drawn in a state diagram since all the states that the system goes through are known. In a nonquasistatic process, the states between A and B are not known, and hence no path can be drawn. .
