I ran the physical experiment on Friday night, interestingly enough there was no temperature difference out of pump/compressor 2 when I heating up the initial temperature from 0 C to 35 C.
I used an inline gas heater with a PID loop, and there is a temperature sensor on the inlet of the pump...
hendersdc, would you mind quickly explaining why flow rate and specific heat should be considered? I'm trying to develop an intuitive understanding of whats happening.
When you say "staying away from the phase transition"; it does reach critical temperature and pressure in the second booster...
I've been leaning towards racookpe1978's approach. In that case can I consider it a linear system so if I raise the initial temperature by 35 C the final temperature will go up by 35 C also?
The CO2 does reach critical temperature and pressure in this system. At 30.95 C (304.1 K) and 1070 psi (7.38 MPa) the density [ρ] is 0.551 g/cm^3, this and the following data are from NIST:
Approaching it as an enthalpy problem hasn't got me anywhere because none of the ∆H = ∆U + ∆(PV)...
CO2 enters the first pump at 300psi 0C, exits at 850psi 30C, enters the second pump, exits at 1200psi 50C. What temperature would it exit the second pump at if the initial temp was 35C?
I've searched the forums, textbooks and after several attempts of calculating I don't think I have the right...
