Condensate Load from Heating Air formula

\(\large{ m_c =   \frac  { 60 \; c_a   \; \gamma_a  \; Q_a  \;   \left(   T_o  \;-\;  T_i  \right)   }  { L_s }   }\)   

Where:

 Units English Metric
\(\large{ m_c }\) = condensate load  \(lbm\) \(kg\)
\(\large{ Q_a }\) = flow rate of air \(\large{\frac{ft^3}{sec}}\) \(\large{\frac{m^3}{s}}\)
\(\large{ L_s }\) = latent heat of steam \(\large{\frac{Btu}{lbm}}\) \(\large{\frac{kJ}{kg}}\)
\(\large{ c_a }\) = specific heat of air \(\large{\frac{Btu}{lbm-F}}\) \(\large{\frac{kJ}{kg-K}}\)
\(\large{ \gamma_a }\)  (Greek symbol gamma) = specific weight of air \(\large{\frac{lbf}{ft^3}}\) \(\large{\frac{N}{m^3}}\)
\(\large{ T_i }\) = inlet temperature of air \(\large{F}\) \(\large{K}\)
\(\large{ T_o }\) = outlet temperature of air \(\large{F}\) \(\large{K}\)
