loss chart shown in the reference. The values of ho and η are required to use the universal loss chart η, which is
given to be 10.016 in this case.
The equation for ho is H / ξ = a/b.
The universal loss chart (Lim Fig. 6), ho vs. Pn, can now be used to extract Pn. By using the curve that is given for
the value η, and ho located at the x-axis, Pn is the corresponding value on the y-axis. The value found for Pn (1.2
W/m) is used to calculate the average losses, P = Pn(H2 / σd). The loss was calculated to be 671.16 W/m2.
Note that this result is for the half plate thickness. The full plate loss is twice the half plate, or 1342.3 W/m2. Results Comparison
