its not a homework problem, I was just curious while reading about the textbook chapter on power cycles, since it is desirable to have high temperature input, I was thinking maybe that temperature can be so high that the temperature of the fluid coming out of the turbine might able to reach...

Since we want the fluid to be in liquid state before entering a boiler, and super-heated water can only reach 374°C before entering super-critical state, suppose after the expansion, the temperature at point 3 is still higher than...
Thank you, I thought the plant transfer function G_p(s) = output(s) / input(s)? how it is independent? are you saying that it always exists but cannot be calculated without some type of inputs?
Homework Statement
c is the coefficient of damping, k is the spring constant, and m is the mass.

Homework Statement
An insulated piston-cylinder device contains 5 L of saturated liquid water at a constant pressure of 150 kPa. An electric resistance heater inside the cylinder is now turned on, and 2200 kJ of energy is transferred to the steam. Determine the entropy change of the water...
ohhh I see! so in another words, the internal energy in the inlet is the same as the internal energy inside the bottle? its 4 am here in New York, I might be brain dead, would this problem be different if the inlet is a cylindrical pipe? sorry if I am asking stupid questions
Thank you very much for taking the time to read all that and answering my questions! I got it now.
I am not sure how to find H and U2 without the tables, are you saying using ideal gas equation to find volume and then H=U2+PV? and ΔU= mass*specific heat of air*change in temperature? but we do...

I came across this problem while practicing for the final exam in thermodynamic,my attempt: i recall this type of problems are not steady-flow system. Since the change in kinetic and...
Homework Statement
Hot and cold streams of a fluid are mixed in a rigid mixing chamber. The hot fluid flows into the chamber at a mass flow rate of 5 kg/s with an energy in the amount of 150 kJ/kg. The cold fluid flows into the chamber with a mass flow rate of 15 kg/s and carries energy in the...
(mentor note: not really a homework as the OP seeks understanding from an article)
