This maintains the heat transfer between steam and liquid to a maximum. Figure 3 shows a temperature profile when saturated steam is used. The difference with the previous diagram is that there is now a layer of condensate on the heating surface and steam temperature is constant.
As a general rule Owls are monogamous - pairs are comprised of one male and one female, neither one of which has any involvement with other nesting birds. With some Owl species the pair bonds last only for the duration of the breeding season, especially if the species involved is dispersive or migratory.
The male, on the other hand, selects a territory while female chooses a nesting site. 1  The clutch size comprises 3 â 11 eggs. 2  The width of an owlâs egg measures at 1.8 inches (4.5 cm). 3  These white eggs stand around 2.2 inches (5.7 cm). 4  The incubation period lasts for about 32 days. 5  The nesting period lasts for 18 â 25 days.
