HEAT AND MASS TRANSFER ISSUES.
1- How is the global heat transfer coefficient
calculated for the walls of an egg brooder? At
equipment walls are composed of two
plywood boards with a layer of fiberglass in
the middle. And to keep all eggs evenly at 40
°C, you use a fan.
2- How is the heat transfer rate of an electrical
conductor wire to the environment
determined? A Cape of plastic insulation
decreases or increases the heat transfer rate
to the environment? There is a point of
inflection for such behavior?
