Question 1.
What is an ideal gas mixture?
Show hintHide hint
Think about behavior without any forces between gas particles.
Question 2.
What does it mean for water vapor to be unsaturated?
Show hintHide hint
Consider when condensation happens.
3Question 3.
What does the assumption of ideal gas allow us to do in psychrometry?
- Calculate real gas effects
- Simplify calculations
- Ignore atmospheric conditions
Show hintHide hint
Think about what ideal gas laws achieve.
4Question 4.
True or False: Unsaturated vapor cannot condense.
- True
- False
Show hintHide hint
Consider the definition of saturation.
Question 5.
You are designing an air conditioning unit for a humid climate. How would the assumptions of ideal gas behavior and unsaturated vapor impact your design choices?
Show hintHide hint
Consider the interactions between temperature and humidity.
Question 6.
Examine the consequences of mistakenly treating water vapor as saturated in a low-humidity environment. What maladaptations could arise in your HVAC design?
Show hintHide hint
Reflect on the definitions of saturated vs unsaturated states.
