Air at a temperature of 27°C (P = 1 atm) and a velocity of 12.7 m/sec flows over the top of a flat mold in order to cool it down (assume this is a flat plate). The mold has dimensions of 1.5 m wide by 0.45 m long (the 0.45 meters dimension is in the direction of the air flow); and is at a temperature of 127°C. a) Find the heat transfer rate from the mold to the air (q). b) Calculate the drag force on the mold due to the air flow.
