Last week we discussed conductive heat transfer in solids. That is, how we feel warmth from a mug of coffee. But why is the handle on the mug so much cooler? One reason, of course, is the greater conductive pathway—or the distance to the heat source—but a more significant reason is probably convection. Heat transfers […]
To understand the effect of wind or forced convection on a surface, we need to understand the basic movement of heat transfer. Thermal energy always moves from hot to cold—unless there is an outside force that changes the natural movement of heat energy.
Whether you are observing an object outside or inside your plant or your […]
