We present the results obtained from experiments on determining condensate flowrate through the annular gaps at locations in which heat-transfer tubes pass through the holes in the horizontal spacer partitions used in vertical steam-water heaters. Expressions for calculating the coefficient of pressure drop due to friction λfr = f(Re) in real gaps are proposed on the basis of the obtained data. © 2011 Pleiades Publishing, Ltd.
