Copper fitting friction loss
Anyone have a friction loss chart for 1/4" ,5/16" , and 3/8" OD copper fittings and copper? I tried ASHRAE, Carrier, Mueller Brass Co., Cello Copper, DuPont, National Refrigerants, RSES, CDA( Copper Development Association ) Handbook," Facilities Piping Systems Handbook " by Michael Frankel and "Piping Practices for Refrigeration Applications" by Stanley Aglow, NOBODY , I MEAN NO ONE, NOBODY has charts for the smaller tubing sizes. Really? And 1/2"OD added 7-30-14 .
