Airflow and Temperature Difference
Supply and return temperatures, air density and specific heat, and the sensible heat equation with a worked example.
Learning objectives
- Apply Q = V̇ × ρ × cp × ΔT with consistent SI units.
- Explain how airflow and ΔT trade off for the same heat load.
- State the assumptions behind a preliminary airflow estimate.
