1. Superheated water vapor at temperature of c, and a pressure of 200 bar, a vapor state at a rate of 10 kg/s is to be saturated is 100 in brought to a process bar an open feedwater This accomplished by mixing this stream with a stream of liquid at 2 and 100 bar (shown below). What flow rate is needed for the liquid stream? (10 marks) Subcooled liqud Superheated saturated vapor Open. feedwater vapor heater with tetrafluoroethane (HFC-

Explanation / Answer

at 200 bar and 500 C, from steam table : enthalpy = h1 = 3060.1

now at 25 C and 100 bar, enthalpy = h2 = 104.766

again at 100 bar ,enthalpy from steam table = hg at 100 bar = 2727.7 KJ/Kg

SO : 10 x 3060.1 + m x 104.766 = (10 +m) x 2727.7

so mass flow of liquid = 1.267 kg/s
