6. We want to make a temperature controller using the diode. Consider your results and suggest which parameter/characteristic of the PN junction diode should be monitored and used for designing the controller. The chosen parameter/characteristic (could be more than one), that is most suitable as the controller input, is expected have most linear (or otherwise reliable) relationship with the temperature.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point. the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
