Homework Statement
An ideal graph is shown in a p-v diagram which looks like one small rectangle inside one large rectangle, with point one on the top right hand corner of the large rectangle leading negatively down to the right hand corner of the small rectangle.
The points of the small rectangle are:
p=2.0^5 Pa
v=0.5 m^3
The points of the large rectangle are:
p=5.0^5
v=1.0 m^3
Homework Equations
My professor said to use the area of the triangle and of the rectangle to calculate the Work.
So which triangle and rectangles do I find the areas of?
Thanks!
The Attempt at a Solution
I have tried different combinations of triangles and rectangle areas for the graph, and cannot come up with the correct answer, which is -1.8^5 J.
Examples:
area small rectangle: 2x10^5*0.5=1x10^5
area large triangle: (5x10^5*1)/2=2.5x10^5
total = 3.5^5 (wrong)
another combination:
area small triangle: (2x10^5*0.5)/2=5x10^4
area large rectangle: 5x10^5*1=5x10^5
total = 5.5x10^5
Thank you for your assistance!
