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. All temperatures are in Kelvin. bT3/2 μ = T+S b = 1.458 x 10-6 kg/(m. s. K¹/2) S S = 110.4 K 0.9 k(T) = k (To) ()* ;k (300 K) = 26.3 x 10-3 W/m.
