Talk:NTU method

Notation
The maths notation, but especially the suffices, need doing properly - trouble is I forget how to use the maths editor over the intervening weeks... Anyone else want to tidy? (I will in due course, else) Linuxlad 12:28, 2 June 2007 (UTC)

I am interested in the article, but don't understand the notation, so would be grateful if it could be expanded. Featherard (talk) 20:55, 20 March 2009 (UTC)featherard

How about definition of terms? What is U ? I don't see it defined anywhere. —Preceding unsigned comment added by Xperrymint (talk • contribs) 06:15, 11 May 2010 (UTC)

U is defined as the overall heat transfer co-efficient. The total heat exchanged between the two fluids in a heat exchanger is equal to UxAxθm (Mean temperature difference) —Preceding unsigned comment added by 122.162.164.129 (talk) 05:16, 4 February 2011 (UTC)

The textbook uses epsilon rather than E for effectiveness. I believe the LaTeX code is \varepsilon. — Preceding unsigned comment added by 173.171.102.20 (talk) 21:10, 13 July 2014 (UTC)

Graph
It would be great to get a graph of NTU vs Effectiveness for different Cr's and an explanation of the graph behavior. Ahlfi006 (talk) 21:55, 27 April 2010 (UTC)
