Re: How do I calculate heat transfer surface?16 October 2013 at 10:10am
The number of plates required is dependent upon the surface area per plate. If you check with local vendors they can typically provide you with a quotation for a unit based on performance requirements. Some general rules of thumb to adhere to are maintaining a shear rate of > 50 Pa, a Reynolds number above 10,000 and a fouling allowance that is roughly 10% of the typical values used for shell and tube heat exchangers. Maintaining a reasonably low inlet manifold velocity will go a long way toward avoiding maldistribution across the plate pack.
