如何计算热损失或者传热系数

题目,the front window of a car is defogged by supplying warm air at 90F to its inner surface, the glass has a thermal conductivity of k=0.8w/m.c with a thickness of 1/4 in. With the supply fan running at moderate speed, the heat transfer coefficient associated with the air is 50 w/m^2.K, Determine the temperature difference of the inner and outer glass, and the heat loss through the glass if the area of the glass is 10 ft^2.
我现在已经在ansys里面求解,通过Nodal里面可以得到温度差,但是不知道怎么看热损失或者传热系数。
还望大虾帮助。

P=A*(Twarm-Tglass_inner)*heat transfer coefficient

传热系数=heat transfer coefficient
