2 cards from this section. Quick, good the night before a test.
What is a polytropic process?
Think about how pressure and volume are related.
Identify the parameters in the work input formula.
What do each of these symbols represent in terms of pressure and volume?
What equation represents the relation in a polytropic process?
Recall the definition of a polytropic process.
True or False: Increasing the polytropic index reduces work input in a compression system.
Consider how 'n' impacts the nature of gas behavior.
Using a two-stage compressor, if P1 = 100 kPa and P2 = 400 kPa with V1 = 0.5 m^3 and n = 1.3, calculate the work input for both stages.
Use the formula for each stage's parameters individually.
Explain how inter-stage cooling could further reduce your calculated work input from the previous problem.
Consider the principles of thermodynamics in compression.
