Unformatted text preview: SP9: 2 kg of saturated liquid water is completely vaporized at a constant pressure of 100 kPa inside a pistoncylinder device. (a) Draw the process on a Pv diagram, accurately labeling the states and showing the values for pressure and specific volume. (b) Determine the change in specific volume (m 3 /kg) during the process. (c) Calculate the work (kJ) associated with the process. (d) Calculate the change in internal energy (kJ) during the process. (e) Calculate the amount of heat transfer (kJ) associated with this process. SP10: An 80 L vessel contains 4 kg of R134a at a pressure of 160 kPa. (a) Locate the state of the refrigerant accurately on Pv and Tv diagrams. (b) What is the temperature (C) of the refrigerant? (c) Determine the quality of the refrigerant. (d) What is the enthalpy (kJ) of the refrigerant? (e) Calculate the volume (m 3 ) occupied by the vapor phase....
