Nondimensional Hot Gas Temperature Increase

Calculates the nondimensional hot gas temperature increase for naturally ventilated enclosures

Equations

\Delta T_g / T_a = 0.63 \cdot \left( \frac{\dot{Q}}{\dot{m} \cdot c_p \ T_a} \right)^{0.72} \cdot \left( \frac{h_k \cdot A_t}{\dot{m} \cdot c_p} \right)^{-0.36}
