Which mode of heat transfer predominates in a vacuum?

Radiation is the primary mode of heat transfer in a vacuum because it does not require a medium for energy transfer and can occur through electromagnetic waves.

What is the Reynolds number used to determine in fluid flow analysis?

The Reynolds number is a dimensionless parameter used in fluid mechanics to predict the flow regime (i.e., laminar, transitional, or turbulent) of a fluid flow based on its velocity, density, viscosity, and characteristic length.

Which of the following materials exhibits the highest strength-to-weight ratio at room temperature?

Carbon fiber reinforced polymer (CFRP) composites offer exceptional strength-to-weight ratios due to the high strength of carbon fibers combined with the low density of the polymer matrix.
