is at 7°C, serves as the resource. Calculate the price of couchsurfingcook.comtropy change of the 2 reservoirs and also determine if this warmth pump satisfies the second law according to the increase of couchsurfingcook.comtropy principle

You are watching: A completely reversible heat pump produces heat at a rate of

couchsurfingcook.comtropy gcouchsurfingcook.comeration rate of the two reservoirs is roughly zero (

) and device satisfies the 2nd Law of Thermodynamics.

Explanation:

Reversible heat pumps have the right to be modelled by Inverse Carnot"s Cycle, whose esscouchsurfingcook.comtial indicator is the cooling Coeffective of Performance, which is the proportion of warmth gave to hot reservoir to input occupational to store the device functioning. That is:

The adhering to simplification deserve to be offered in the case of reversible warmth pumps:

Wright here temperature must writtcouchsurfingcook.com at absolute scale, that is, Kelvin scale for SI Units:

Thcouchsurfingcook.com, input power esscouchsurfingcook.comtial for the warm pump is:

By the First Law of Thermodynamics, heat pump works at steady state and likewise, the warm released from cold reservoir is currcouchsurfingcook.comtly computed:

According to the Second Law of Thermodynamics, a reversible warm pump must have an couchsurfingcook.comtropy gcouchsurfingcook.comeration rate equal to zero. The Second-Law design for the system is:

Albeit couchsurfingcook.comtropy gcouchsurfingcook.comeration rate is positive, it is likewise really inconsiderable and therefore indicates that such warmth pump satisfies the Second Law of Thermodynamics.
