Q 4. Two streams of water are mixed with one stream of saturated steam at 3.2 bar (gauge) to form the feed to a boiler. Process data as follows; Feed water 1 120 kg/min @30°C Feed water 2 240 kg/min @46°C Feed steam 3 108 kg/min @ 3.2 bar pressure (gauge) through a 7.5 cm-ID pipe Outlet steam @Boiler pressure 25 bar. The outlet stream emerges from the boiler through a 8 cm ID pipe. Calculate the required heat input to the boiler in kilo-watts, if the emerging stream is saturated at the boiler pressure. Neglect the kinetic energies of the liquid water inlet streams.

Question
Two stream of water
Transcribed Image Text:Q 4. Two streams of water are mixed with one stream of saturated steam at 3.2 bar (gauge) to form the feed
to a boiler. Process data as follows;
Feed water 1
120 kg/min @30°C
Feed water 2
240 kg/min @46°C
Feed steam 3
108 kg/min @ 3.2 bar pressure (gauge) through a 7.5 cm-ID pipe
Outlet steam
@Boiler pressure 25 bar.
The outlet stream emerges from the boiler through a 8 cm ID pipe. Calculate the required heat input to the
boiler in kilo-watts, if the emerging stream is saturated at the boiler pressure. Neglect the kinetic energies
of the liquid water inlet streams.
