Normal cubic meters per hour

RUP 3 Nrn /hr Reid vapour pressure normal cubic meters per hour... 

Acquired, installed and operated an electrolyzer which produces 10 normal cubic meters per hour (approximately 1 kilogram per hour) hydrogen. Tested the purity, dryness, flow rate, and hydrogen delivery pressure, for compatibility with Energy Conversion Devices, Inc. s (ECD s) (Ovonic) metal hydrides. 

N or N2 = nitrogen = an inert gas, comprising about 80% of air and a large part of poc, unless using oxygen enrichment, net heating value = nhv = lower heating value, Ihv. See Ihv. neutral pressure plane = zero pressure plane = balanced pressure line (invisible), or level at which the pressure inside a furnace is exactly equal to the pressure outside the furnace at the same elevation. Usually not really a plane, but an invisible surface rumpled by burner jet and draft effects. See sec. 6.6.1. nm /h = normal cubic meters per hour, a unit of volumetric flow rate, equal to 37.9 scfh. nm is standardized at 0 C, 760 mm Hg, dry air or gas. A standard ft is defined at 60 F, 30 Hg, saturated air or gas. normal air = European near-equivalent of U.S. standard air , see also).
