+// Temperature of air in C is given as:
+Tinfinity = 20;
+// Temperature of surface in C is given as:
+Ts = 100;
+// Therefore avaerage temperature in degree C would be:
+Ta = (Ts+Tinfinity)/2;
+// From fig. 4.2 on page 232, it can be easily seen that (deltaT/deltaY) at
+// y=0 is -66.7 K/mm
+// From Table 28 in Appendix 2, at average temperature of air, thermal
+// conductivity in W/m-K is
+k = 0.028;
