Heating Coil Sizing Calculation

https://3d-labs.com/product/heating-coil-sizing-calculation/

 Vessels can be heated in a number of different ways.  This module will
 deal with indirect heating. In these systems, the heat is transferred across
 a heat transfer surface. The optimal outer radius was obtained by several 
 simulations on the tank with different outer radius of the heater , and the
 required heating surface and diameter of the coil pipe were also calculated.
