Unformatted text preview: Department of Mechanical Science and Engineering ME 300 Thermodynamics Section D Fall 2010 Homework #4 due Friday, September 24 th Problem 4.1* Determine the specific volume of refrigerant-134a vapor at 15 bar and 70 C using: (a) the ideal-gas equation. (b) the generalized compressibility chart. (c) tables. (d) Determine the error, in %, for cases (a) and (b) when compared to your answer from part (c). Problem 4.2 Complete the following table by using the steam tables (Table A-1 to A-5) T p h x Phase Description C kPa kJ/kg- (a) 1250 (b) 100 3500 (c) 450 0.85 (d) 240 1500 (e) 2700 1 Problem 4.3 (a) On the attached P-v diagram for R-134a sketch the constant temperature process through the interme- diate state p i =360 kPa, v i =0.03 m 3 /kg as pressure changes from the initial state of p 1 =1000 kPa to the final state p 2 =60 kPa. Mark the three states on the diagram and use arrows to indicate the direction of the process. Determine the temperature of the process and label the isotherm (dashed line in diagram)the process....
