Question

A plane wall with surface temperature of 350°C is attached with straight rectangular fins (k = 235 W/m·K). The fins are exposed to an ambient air condition of 25°C and the convection heat transfer coefficient is 154 W/m2·K. Each fin has a length of 82 mm, a base of 5 mm thick and a width of 100 mm.

Answer 1

Determine the efficiency, heat transfer rate, and effectiveness of each fin.

Answer:

The efficiency of fin is 64.2%,

heat transfer rate 543.03W and

effectiveness of each fin is 21.67.
