A closed, rigid tank contains a two-phase liquidvapor
Chapter 3, Problem 3.26(choose chapter or problem)
A closed, rigid tank contains a two-phase liquid–vapor mixture of Refrigerant 22 initially at \(-20^{\circ} \mathrm{C}\) with a quality of 50.36%. Energy transfer by heat into the tank occurs until the refrigerant is at a final pressure of 6 bar. Determine the final temperature, in \(^{\circ} \mathrm{C}\). If the final state is in the superheated vapor region, at what temperature, in \(^{\circ} \mathrm{C}\), does the tank contain only saturated vapor?

ANSWER:Problem 3.26
A closed, rigid tank contains a two-phase liquid vapor mixture of Refrigerant 22 initially at -20°C with a quality of 50.36%. Energy transfer by heat into the tank occurs until the refrigerant is at a final pressure of 6 bar. Determine the final temperature, in °C. If the final state is in the superheated vapor region, at what temperature, in °C, does the tank contain only saturated vapor?
Step by Step Solution
Step 1 of 3
Rigid tank which mean that the process is a constant specific volume process
State(1)
- Two phase liquid-vapor mixture of refrigerant 22.
- The temperature
- The quality
State (2)
- The pressure
Assume system is in equilibrium
State(1)
From table A-7
Then the volume is defined by
