Suppose the following reaction is carried out in a chemical reactor: A+ B C. The reactor has a single inlet and a single effluent (outlet) and the entire reactor system is at constant density ( ρ = 0.9kg / L ). The desired conversion of A is 0.8.

Webnight, all terms become much smaller; as before, radiative cooling is mainly balanced by ground heat flux. The last example is a Douglas fir forest (Fig. 10.4). Here latent and sensible heat fluxes are comparable during the day. The storage and ground heat flux are lumped in the curves, but for deep forest, the storage term dominates. In spite of the enormous transfers of energy into and from the Earth, it maintains a relatively constant temperature because, as a whole, there is little net gain or loss: Earth emits via atmospheric and terrestrial radiation (shifted to longer electromagnetic wavelengths) to space about the same amount of energy as it receives via solar insolation (all forms of electromagnetic radiation).
