Air at 1 atm is trapped between two square horizontal plates (W = 1 m and H=1 m). One plate is at 150 °C, while the other is at 40 °C. The distance between the plates is 25 mm. Ignoring the radiative heat transfer, What is the heat transfer rate (in Watts)? Choose the closest one. Air Properties Correlations.
