dTª tubo respecto de Ts y Salto_termico

Salto_termico: Al aumentar el salto térmico, aumenta ( paradójicamente) la diferencia: Ts -Ttubo --> Es lógico, debe estar el tubo más caliente para que se transmita más rapido el calor.

Ts: Al aumentar Ts, Ttubo aumenta exactamente en el mismo valor. Se mantiene constante : Ts - Ttubo

A continuación una muestra. Los resultados son inválidos debido al no. de Reynols, que es muy bajo para la expresion utilizada. Pero la idea sirve.
Ts = [ 120:10:260 ];
salto_termico = [1:15];

Ttubo =
