Answer to Question #269709 in Mechanical Engineering for lone

Question

Two kg of air in a closed system undergoes an isothermal process from 606 kPa and 200°C to 75 kPa. The heat transfer (expressed to ZERO decimal places) during the process is in kJ:

From the tables (air is assumed as ideal gas based on given conditions), the gas constant for air:  R = 0.2870 kJ/kg·K.

Answer 1

Answer with the diagram and the table is given below:

Note:you can also use 606 and 75 value here you will get the results accurate.
