Homework SourseA condensate return flow RC1 occurs from the drop in piped s
A condensate return flow, RC1, occurs from the drop in piped steam pressure as it is transported from a boiler room, Steam1, (at pressure 6.6 bar) to a lab, Steam2, (at pressure 6.4 bar). Mass flow of Steam2 = 0.003333 kg/s. Using the perfect gas law, and assuming the volumetric flow rate of Steam1 and Steam2 are equal estimate the condensate return mass flow and Steam 1 mass flow
Solution
Steam at 6.6 bar
specific volume = 0.288 m^3/kg
Steam at 6.4 bar
specific volume = 0.297 m^3/kg
Volume flow rate of steam 1 and steam 2 are equal
=> 0.003333 * 0.297 = m * 0.288
Steam1 mass flow rate = 0.003437156 kg/s
Condensate return = m1 - m2 = 0.003437156 - 0.003333 = 0.000104 kg/s
