State whether each statement below is True (T) or False (El. Use your best engineering judgment". 1. Phenomenological laws classify and describe phenomena based on observation of macroscopic behavior without explanation of microscopic behavior. 2. Fourier's Law of Heat Conduction states that the heat flux is directly proportional to the temperature gradient. 3. A "gray surface" absorbs the same magnitude of radiation as a “black surface". 4. A "black surface" surfaces emit less radiation than does a "gray surface". 5....

6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
