As mentioned earlier in the article the convection heat transfer coefficient for each stream depends on the type of fluid flow properties and temperature properties.
The calculator is generic and can be used for both metric and imperial units as long as the use of units is consistent.
Air h 10 to 100 w m 2 k water h 500 to 10 000 w m 2 k.
The heat transfer convection coefficient for air is 50 w m2k.
Typically they are malleable and ductile deforming under stress without cleaving.
The conductive heat transfer through the wall can be calculated.
Other influences include the temperature difference across the metal the thickness of the metal and the surface area of the metal.
For example the initial temperature of the metal can make a huge difference to its heat transfer rate.
