QUESTION:
Problem 135HP
Use the computer software to sketch the variation of pressure with temperature in Problem 2.44. Extend the curve slightly into the single-phase region.
Problem 2.44
A sealed rigid vessel has volume of 1 m3 and contains 2 kg of water at 100°C. The vessel is now heated. If a safety pressure valve is installed, at what pressure should the valve be set to have a maximum temperature of 200°C?
ANSWER:
Solution 135HP
Step 1 of 2:
We are going to plot the variation of pressure with respect to the temperature.
The volume of the vessel V =1 m3
The mass of water m = 2 kg
The temperature T = 100°C
The specific volume
The specific volume for the process is 0.5 m3/kg.
The values of pressure with respect to the temperature at 0.5 m3/kg is given by thermodynamic software CATT 3 (Computer Aided Thermodynamic Table 3).
