Titanic's Propulsion Plant

[4] The High Pressure (HP) cylinder radius was R = 27 inches, and its stroke was L = 75 inches. The total HP cylinder volume was therefore = p R 2 L = 171,767 cu-inches. Assuming 42% cutoff for 75 revolutions (based on the ratio of specific volume for saturated steam at pressures of 230 psia input and 93 psia output) we get a steam intake volume equal to V = 0.42 x 171,767 = 72,142 cu inches

Steam Calculators: Boiler Calculator

Mar 17, 2015Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
