Show that Equations 13.32 and 13.33 apply to an exchanger in which there are N parallel tubes

Question:

Show that Equations 13.32 and 13.33 apply to an exchanger in which there are N parallel tubes of identical diameter if D is simply replaced by ND.

Equations 13.32 Qs h DL = = -Q hT DL = A e(1-A) L/B L 1 L [T,(x) T,;(x)]dx = AT0 + (Tio Tso) B (e(1-A)L/B - 1) - (1-A) L
