Thermal Convection and Radiation Values

This is a collection of thermal convection, radiation, and solar heating values for easy comparison to one another.

Pipe Network

Note that all equivalent liquid structures have the same values as their gas counterparts, except for the Liquid Pipe Convection Radiator which is listed separately.

Insulated tanks, pipes and in-line tanks have zero for all values.

Solar heating does not seem to apply to pipe-mounted radiators.

Heat Exchangers

Heat exchangers are different from most other atmospheric devices because they operate between pipe networks instead of an internal volume and outside atmosphere. Heat transfer between two networks follows the same rules as thermal convection.

Counterflow heat exchangers are not easily comparable to direct heat exchangers. See external link below.
