Since water is considered non-compressible, in a closed-loop system, this thermal expansion puts an incredible amount of pressure on the piping and components of the entire system. (2) Lengths (5) Nominal HP's are to assist you to obtain a "rough" unit size at each evaporating temperature (@ 40C condensing temperature). This week we turn our attention to the condensate outlet. The condenser transfers the heat from the hot gas to the cooler pool water circulating through the heater. This standard explains colors, text, size, and placement of pipe marking labels. 1 discussed above are also included in ASHRAE 189. Years of trouble-free service in installations here and abroad have built a new reputation for copper piping in its modern form—light, strong, corrosion resistant tube. 9 Note: General accepted industry practice for determining the equivalent lengths for both P traps and U Bends is to add two 90° LR elbows of the specific OD tubing size for each component used. Calculation of pressure drops of flowing liquids and gases in pipes and pipe elements (laminar and turbulent flow). The net result for the engineer that uses Stainless steel piping, which complies with ASTM A403 for type 316 with similar fittings using welded or grooved couplings is used for both larger domestic water piping and direct replacement of copper piping.
