Sample Thermodynamics Problems Solution
Question 2. A gas in a piston-cylinder assembly undergoes a compression process for which the relationship between pressure and volume is given by 𝑝𝑉1.3=𝑐𝑜𝑛𝑠𝑡𝑎𝑛𝑡. The initial pressure is 67 lbf/in2, initial volume is 7.4 ft3 and the final pressure is 140 lbf/in2.
- a) State the engineering model
- b) Draw p-v diagram
- c) Calculate the final volume, in ft3
- d) Determine the work done during the process, in Btu.
