### Condensate Recovery Pressure Loss through piping Formula

$$p_l = 1000 \; \mu \; l \; v_c^2 \;/\; 2\;d \; V_{temp}$$
Symbol English Metric
$$p_l$$ = condensate pressure loss $$lbf \;/\; in^2$$ $$Pa$$
$$v_c$$ = condensate velocity $$ft \;/\; sec$$ $$m \;/\; s$$
$$\mu$$  (Greek symbol mu) = friction coefficient $$dimensionless$$
$$d$$ = inside diameter of pipe $$in$$ $$mm$$
$$l$$ = pipe length $$ft$$ $$m$$
$$V_{temp}$$ = temporary specific volume variable $$ft^3 \;/\; lbm$$ $$m^3 \;/\; kg$$

### Condensate Recovery Velocity through piping Formula

$$v_c = 1000\;m_c \; V_{temp} \;/\; 3.6\; \pi \; ( d \;/\; 2 )^2$$
Symbol English Metric
$$v_c$$ = condensate velocity $$ft \;/\;sec$$    $$m \;/\; s$$
$$m_c$$ = condensate load   $$lbm$$  $$kg$$
$$d$$ = inside diameter of pipe $$in$$ $$mm$$
$$\pi$$ = Pi   $$3.141 592 653 ...$$
$$V_{temp}$$ = temporary specific volume variable $$ft^3 \;/\; lbm$$ $$m^3 \;/\; kg$$

### Condensate Recovery Steam Pressure Loss through piping Formula

$$p_l = \mu \; l \; v_s^2 \;/\; 2\;d \; V_{temp}$$
Symbol English Metric
$$p_l$$ = steam pressure loss $$lbf \;/\; in^2$$ $$Pa$$
$$\mu$$  (Greek symbol mu) = friction coefficient $$dimensionless$$
$$d$$ = inside diameter of pipe $$in$$ $$mm$$
$$l$$ = pipe length  $$\large{ ft }$$    $$\large{ m }$$
$$v_s$$ = steam velocity $$ft \;/\; sec$$  $$m \;/\; s$$
$$V_{temp}$$ = temporary specific volume variable $$ft^3 \;/\; lbm$$ $$m^3 \;/\; kg$$
