Question

One pound-mass of water fills a 2.4264-ft3 weighted piston-cylinder device at a temperature of 6008F. The piston- cylinder device is now cooled until its temperature is 2008F. Determine the final pressure of water, in psia, and the vol- ume, in ft

Answer 1

Step-by-step explanation:

find the initial specific volume

`v_(1) =V_(1) /m=2.4264ft^3/1lbm=2.4264ft^3/lbm`

To find pressure

`T_(1) =600F , v_(1) =2.4264ft^3/lbm\\so\\P_(1) =P_(2) =250psia`
