First,we need to admit that all pipe size should be identified as nominal pipe size (NPS).Second,for NPS 1/8 (DN 6) to NPS 12 (DN 300),these are based on a standard outside diameter (O.D.) This O.D.was originally selected to specify pipe dimension,but as the pipe always have an wall thickness and internal diameter (ID).Condensate Load CalculationNov 11,2012 Sizing Steam Pipes kg h#0183;Q = quantity of condensate (kg/hr) W = total weight of pipes (kg) T = saturation steam trap temperature (o C) t = initial temperature of pipe (o C) usually surrounding air temperature.m = minutes of heating up system.L = latent heat of steam (Btu/hr) For the case above W = 500 L x 1 (m3 / 1000 L) x 1000 (kg/m 3) = 500 kg.T = 100 o C.t = 22 results for this questionWhat is the size of a steam pipe?What is the size of a steam pipe?Sizing Steam Pipes (kg/h) Steam is a compressible gas where pipe line mass flow capacity depends on steam pressure.Steam is a compressible gas where mass flow capacity of pipe lines depends on steam pressures.Sizing Steam Pipes (kg/h) - Engineering ToolBox
