## Condensate Pipe Sizing formula

 $$\large{ d = 12\; \sqrt { \frac { 4 } { \pi } \; \frac { m_c \; \upsilon } {3600 \;v_c} } }$$

### Where:

 Units English Metric $$\large{ d }$$ = pipe inner diameter $$\large{in}$$ $$\large{mm}$$ $$\large{ m_c }$$ = condensate load $$\large{lbm}$$ $$\large{kg}$$ $$\large{ \pi }$$ = Pi $$\large{3.141 592 653 ...}$$ $$\large{ \upsilon }$$  (Greek symbol upsilon) = specific volume of condensate $$\large{\frac{ft^3}{lbm}}$$ $$\large{\frac{m^3}{kg}}$$ $$\large{ v_c }$$ = velocity of condensate $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$
