Calculation of K-values for Pipe Size Changes K-value relationships for several common geometries of pipe size expansion and reduction are given below. This rainfall depth is often recommended for sizing GI structures because it will treat ~90% of all of rainfall runoff that occurs during a year of average precipitation. of course you must calculate your pipe for the biggest load It is simple and not for each pipe branch you calculate your full load capacity then work out pipe size you put together (add) each branch load and you calculate your header for full load, but as evaporators are installed apart each other, then after each evaporator your header must be increased in size for added load. Since the pressure at 1 will be higher than the pressure at 2 (for flow moving from 1 to 2), the pressure difference as defined will be a positive quantity. There are 2 key aspects to sizing your piping correctly: max system CFM requirements and minimum required operating pressure. With every 100′, you lose 6′ of head lose and you need at least 5′ of head loss so your circulators do not “cavitate”. 85, 30C = 0. The length of pipe from the gas meter to the most remote outlet (outlet A) is 60 feet. Try out our handy pipe resistance calculator that can give you significant cost savings when installing the right pump with the correct piping system. com and how to find solution for your fluid flow problem.
