In this short video lecture, we solve a sample exam problem from heat transfer. Topics covered include heat exchangers, thermal resistances in series, overall heat transfer coefficient, boiling, solving for outlet temperature. This problem was a continuation of a previous problem, which can be found here ( • Heat Transfer Crash Course: Example exam p... ). To solve this problem using the effectiveness - NTU method, where NTU stands for number of transfer units, go to this link ( • Heat Transfer Crash Course: Example exam p... ).
