Problem 264EUP
A rigid tank holds 1.5 lbm R-410a at 100 F as saturated vapor. The tank is now cooled to 60 F by heat transfer to the ambient. Which two properties determine the final state? Determine the amount of work and heat transfer during the process.
ANSWER:
Solution 264 EUP
Step 1 of 2
We have find the two properties which determine the final state of R-410a and also the amount of work and heat transfer during the process.
The two properties which determine the final state of R-410a are specific volumeand internal
energy
The amount of work done during the process can be found using the expression.
Where,
constant pressure in psia
change in the volume in ft3
The saturated R-410a vapour is contained in a rigid tank, so there is no change in the volume.
Hence,
