Entropy production in mixing

Example 1.6 Entropy production in mixing Consider the following two mixing processes  

Mixing process 1 In a steady mixing process, 14.636kg/s of saturated steam (stream 1) at 133.9kPa is mixed with 15.0kg/s of saturated steam (stream 2) at 476kPa. 

Determine and compare the rate of entropy production and the lost work for these two mixing processes producing a product of stream 3. 

Assume that the surroundings are at 298.15 K and the kinetic and potential energy changes are negligible. Mixing process 1 Available data from the steam tables in Appendix D are
