Question

c. State the Kelvin-Planck statement of the 2ad law in your own words What is the definition of an irreversible process? Give 5 examples of irreversible processes that you experience in your daily life d. e. f Suppose two cycles have the same heat source and heat sink (i.e. are operating between the same two thermal reservoirs). i. How will their efficiencies compare if they are both reversible? Why? ii. How will their efficiencies compare if one is reversible but the other contains irreversibilities? Why? g. If you had a power cycle and were able to eliminate all the irreversibilities h. What are the equations for the efficiency of a power cycle achieving the i. How can the first law of thermodynamics be used to determine whether a j. How can the 2nd law of thermodynamics be used to determine whether a k. How will the efficiency/coefficient-of performance of a real power (friction, etc.), what would its efficiency be equal to? maximum possible work output and the coefficients of performance for a refrigerator and a heat pump with the minimum possible work input? cycle is possible? cycle is possible? cycle/refrigerator/heat pump compare to the efficiency/coefficient-of- performance of a Carnot power cycle/refrigerator/heat pump?

Explanation / Answer

Answer#c#

Kelvin-Planck statement basically deals with heat engine and negative in nature. It simply states that we can't produce 100% work from single thermal reservoir.
