Question

Three different samples of R-134a as a saturated vapor are obtained at (a) -40 degC, (b) 0 degC and (c) 40 degC. 1. Sketch the P-v and T-v diagrams for R-134a and locate the states for each of these samples. 2. For each of the samples, determine the specific volume and pressure for the R-134a using the tables. 3. For each of the samples, determine the specific volume for the R-134a using the ideal gas law. 4. For each of these samples, determine the percent relative error in the specific volume that results from using the ideal gas law relations. \% \text { relative error }=\frac{\left(v_{\text {ideal }}-v_{\text {gastables }}\right)}{v_{\text {gas tables }}} * 100
