Thermodynamics 3-Hacmi 2 m3 olan kapalı bir kap 200 kPa basınçta 4 kg doymuş sıvı ve doymuş buhar karışımı su bulundurmaktadır. Sıcaklığı 160⁰C olan çevreden kaptaki suyunu tamamı doymuş buhar oluncaya kadar ısı verilmektedir. Not: T(K) = 273 + ºC a)Sistemin entropi değişimini bulunuz. b)Kab'a yapılan ısı transferini bulunuz. c)Toplam entropi değişimini bulunuz

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

Aheavily insulated piston-cylinder device contains 0.02 m3 of steam at 300 kpa and 200 °c. 1.2 mpa. d this process. team is now compressed in a reversible manner to a pressure of etermine the entropy change and the work done on the steam during this process
