Water flows steadily through a device at a flow rate of 20 kg/s. At the inlet, the conditions are 200 kPa and 10oC. At the exit, the conditions are 2000 kPa and 50oC.
(a) Determine the difference between the entropy (S) transported by the flow at the exit and at the inlet.
(b) What are the possible reasons behind the increase in entropy transport?
