LW-9539 Natural & Forced Convection Experiment

Purposes
1. Standard airflow rate generator and calculation
1.1 The apparatus is based on AMCA210-07 Standard,
   which is widely used in industries.
1.2 Students can understand flow rate measurement by operating and calculating
   themselves.
2. Convection coefficient, h
2.1 Describe convective condition by Newton’s law of cooling: Q = h × A × △T
2.2 Study convection coefficient under different natural or forced convective
   conditions, airflow rate and models.
3. Get the concept of heat dissipation
3.1 By observation, record and calculation
3.2 Helpful to know the overall issue of cooling and thermal management
