Question: Part Description Answer Save Status A. The calculation to find work from a to b is: (600kPa-120kPa)(.5m 3 -.2m 3 ) -(600kPa-120kPa)(.5m 3 -.2m 3

Part Description Answer Save Status
A.

The calculation to find work from a to b is:

(600kPa-120kPa)(.5m3-.2m3)

-(600kPa-120kPa)(.5m3-.2m3)

(600kPa)(.5m3-.2m3)

-(600kPa)(.5m3-.2m3)

(120kPa)(.5m3-.2m3)

-(120kPa)(.5m3-.2m3)

No calculation required. W = 0

B.

Using the figure from part A, the calculation to find work from b to c is:

(600kPa-120kPa)(.5m3-.2m3)

-(600kPa-120kPa)(.5m3-.2m3)

(600kPa)(.5m3-.2m3)

-(600kPa)(.5m3-.2m3)

(120kPa)(.5m3-.2m3)

-(120kPa)(.5m3-.2m3)
