APPENDIX B HEAD LOSS CALCULATIONS FOR XPA PIPE AND PEX TUBING The following Appendix provides head loss information for XPA pipe and PEX tubing over a range of flow rates and liquid temperatures. Tables have been developed for 100% water as well as for a range of glycol/water mixtures typically used in hydronic systems. For operating conditions not covered by the following tables contact IPEX for further information. IPEX follows ASHRAE principles for head loss calculation. In particular, the Friction Factor formula used is a function of the Reynold’s Number - see below.
friction factor f = 64 / Re#
if
Re# < 3,000
f = 0.3164 / Re#^0.25
if
3,000 < Re# < 10,000
f = 0.0032 + 0.221 / Re#^0.237
if
Re# > 10,000 head loss (m)
Reynolds #
H = f (L/D) (v^2 / 2g)
Re# = v d D / u
velocity (ft/sec)
v = velocity d = inside diameter D = density u = viscosity
v = velocity L = length D = diameter f = friction factor g = 9.81
v=y/A y = flowrate A = cross section area
