Two very large gray planes are at the constant temperatures of T1 and T2. If the two gray planes have emissivities of ε1 and ε2, respectively, what is the net heat exchange rate per unit area
Dittus-Boelter equation, NNu=0.023 (NRe) (NPr)n, where n = 0.4 for hot fluid and n = 0.3 for cold fluid, is applicable for
