Heat Transfer by Convection

Heat transfer by convection occurs when a fluid (liquid or gas) transfers heat between a solid surface and itself. The rate of heat transfer (Q) during convection can be calculated using the formula Q = h * A * ΔT, where h is the heat transfer coefficient measured in watts per square meter per Kelvin (W/m²·K), A is the surface area through which the heat transfers measured in square meters (m²), and ΔT is the temperature difference between the surface and the fluid measured in Kelvin (K) or degrees Celsius (°C).

Understanding convection is essential in various fields such as HVAC (heating, ventilating, and air conditioning) design, automobile engine cooling systems, and estimating heat transfer in environmental contexts.
