Homework Statement
A closed system consisting of 2 lb of a gas undergoes a process in which pV^n=constant. For: p1=20 lb/in^2 , V1=10 ft^3 and p2=100lb/in^2 V2=2.9 ft^3
(a)What is n ?
(b)What is the specific volume at states 1 and 2 in ft^3/lb?
(c)Sketch the process on pressure-volume coordinates
For (a), I don't need to convert the units all to feet or all to inches right? i can just say p1V1^n=p2V2^n correct?
(b) Is just a matter of find the mass m=Weight/g
(c) Is confusing me? Is this just a graph? With p on the horizontal axis and V on the vertical?
Thanks!
