Since the mass of air is 39 kg, calculate the entropy change that occurs during this heating process (You can use the ideal gas equations for air).arrow_forward2 mol of an ideal gas expands from 1 L to 10 L reversibly and isothermally at 250 K.

- Steam at 4 MPa and 350°C is expanded in an adiabatic turbine to 125 kPa. What is the isentropic efficiency of this turbine if the steam is exhausted as a saturated vapor? Plot both the actual process and the referenced isentropic process in T-s diagram with saturation lines. Hint: We worked on a similar problem in class (example 7-15 for compressor, ideal gas). It will be helpful to study example 7-14 (turbine, saturated mixture) in the textbook before you start this problem.arrow_forwardNOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air is compressed by an adiabatic compressor from 95 kPa and 27°C to 600 kPa and 277°C.

The exit temperature of air is OK.arrow_forwardInsulated container X and uninsulated container Y are connected with a valve both initially containing water steam. The initial state at X is 400kPa and x=80% where the volume is 0.2 m'. Container Y initially contains 3kg steam at 200kPa and 250°C. The valve is opened until the pressure in both containers is equal and 300kPa, and during this process 900 kJ heat is transferred from container Y to the surroundings.
