"WebTubes can be finned on both the interior and exterior. This is probably the oldest form of heat transfer enhancement. Finning is usually desirable when the fluid has a relatively low heat transfer film coefficient as does a gas. The fin not only increases the film coefficient with added turbulence but also increases the heat transfer surface area. " - How does heat capacity increase heat transfer

How does heat capacity increase heat transfer

WebWater has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H 2 in H 2 O) and the breaking of hydrogen bonds absorbs heat. With a such a high heat capacity, a lot of heat energy can enter a ...
