Which of the following can be stated about irreversible proc

Which of the following can be stated about irreversible processes? Entropy generation is equal to 0 for the process. Entropy generation is less than zero for the process. Entropy generation is greater than zero for the process. Which mode of energy transport can be ignored for closed systems? Heat transfer Work Mass transfer

Solution

>> As, ds >= 0, for all feasible systems

>> For reversible system, entropy generation = 0

and, for irreversible system, entropy generation is greater than zero for the process.

>> So, option (c) is correct

>> Solution 2

As, in Closed System, only mass is conserved and energy of system keeps varying.

So, Mass Transfer of energy transport can be ignored for closed systems.
