Question

Air at 20 °C and 1 atm. flow over a flat plate with 35 m/s. The size of the plate is 75 cm by 75 cm and is maintained at 60 °C. Calculate:
a) The heat transfer rate 40 cm from the leading edge of the plate. (5 points)
b) The heat transfer rate at the end of the plate (at x = L). (5 points)                                  
c) The heat transfer rate from the entire plate. (10 points)                                                                
d) The heat transfer rate at the end of the hot plate if it is preceded by unheated                                   section of 25 cm. (10 points)     

1- Draw a clear schematic for (a) and (d)
2- choose a good equation from chapter 7 in book of (heat and mass transfer by Incropera 6e)

3-part d is unheated section use the equation that is related to this topic

4- clarify at what temperature you get the properties
