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

Answered by maham237 @ 22/02/2021

Explanation:

find the initial specific volume

$v_{1} =V_{1} /m=2.4264ft^3/1lbm=2.4264ft^3/lbm$

To find pressure

$T_{1} =600F , v_{1} =2.4264ft^3/lbm\\so\\P_{1} =P_{2} =250psia$
