Condensate Drain Pipe Size Calculation

Lines consisting of two phase flow such as trap discharge lines which are selected according to the pressures either side of the trap.

Condensate drain pipe size calculation.

When sizing condensate return lines in steam distribution system remember that the maximum condensate flow is achieved during plant start up when pipes and equipment are heated up. We usually size condensate drain based on nominal tonnage. The steeper the grade of the installed pipe the more water it will carry. Equations displayed for easy reference.

Interesting question i don t know that i ve ever calculated it. 3 4 is sufficient for up to 20 tons according to the imc unless the drain outlet size is larger than 3 4. The condensate pipe siz ing chart. The calc is based on lbs of dry air and grains of moisture per lb.

A particular pipe size on a given grade will only carry a certain amount of water. Where cities allow drywells they work fine. Imc 307 2 2 tells us that an a c condensate drain inside diameter should not be smaller than 3 4 and should not be smaller than the drain pan outlet diameter. Ipc chapter 8 table 8 2 minimum condensate pipe size shows the equipment capacity in tons or kw and the minimum pipe size you can use.

2 tons 5 tons 1 30 tons 1 50 tons 1 175 tons 2 etc. First calculate the mixed air condition. Upvote 3 downvote 0 reply 1. A rule of thumb the condensate load used to design condensate pipe lines should be twice the maximum production load.

Per code condensate drain lines must be tied into the sanitary drain system by means of an indirect waste connection. The condensate pipe sizing chart figure 14 3 5 can be used to size any type of condensate line including. Air change rate calculator air mixing condensate generated cooling load sanity check duct size calculator exhaust hood cfm fluid mixing calculator psychrometric calculations vapor pressure deficit vpd window u shgc values default general calculators. The chart figure 14 3 5.

The prinsco drainage calculator estimates the capacity of tile drainage systems. Checks the capacity of drain tile on existing drainage systems. Also you should be able to calculate the amount of moisture being condensed and then size the pipe based on sanitary pipe sizing per code. Sizes the piping needed on the acreage to.

Drain lines containing no flash steam. If value not known use pipe friction calculator to determine resistence of piping in feet of head. If value of 0 entered calculator assumes proper diameter for discharge pipe velocity of 10 ft sec or less and includes a safety margin of 10 psig. Online calculator to quickly determine condensate recovery pipe sizing for condensate recovery line by pressure loss.
