Consider R-134a as the substance.
(a) Find the specific volume (ft3/lbm) and specific entropy (Btu/lbm-R) when P = 90 psia and h = 125.695 Btu/lbm.
(b) Find the pressure (psia) and specific volume (ft3/lbm) when T = 60?F and s = 0.10305 Btu/lbm-R.
(c) Find the specific volume (ft3/lbm) and specific entropy (Btu/lbm-R) when P = 80 psia and T = 40oF.
(d) Locate states (a), (b), and (c) on P-v and T-s diagrams for R-134a. Label states, show property values, and indicate appropriate lines of constant temperature or pressure.
