Answer:

Explanation:

The solid state is one of the 3 stages which matter undergoes in addition to the liquid and the gaseous state. Matter in it's solid state contains atoms which are closely packed, In this stage, matter exhibits the least amount of kinetic energy of all three stages hence hindering movement of its particles and exhibiting firmness and rigidity. Solids exhibits a regular arrangement of it's molecules which differs from the scattered nature of gaseous particles and slightly ordered nature of liquid molecules. Solids exhibits a defined volume , and shape with molecules held together by string attractive forces. Solids can change into liquid through melting or transform directly into gaseous state through sublimation.

Determine the minimum work per unit of heat transfer from the source reservoir that is required to drive a heat pump with therma
Sloan [31]

Answer:

The minimum work per unit heat transfer will be 0.15.

Explanation:

We know the for a heat pump the coefficient of performance (C_{HP}) is given by

C_{HP} = \dfrac{Q_{H}}{W_{in}}

where, Q_{H} is the magnitude of heat transfer between cyclic device and    high-temperature medium at temperature T_{H} and W_{in} is the required input and is given by W_{in} = Q_{H} - Q_{L}, Q_{L} being magnitude of heat transfer between cyclic device and low-temperature T_{L}. Therefore, from above equation we can write,

&& \dfrac{Q_{H}}{W_{in}} = \dfrac{Q_{H}}{Q_{H} - Q_{L}} = \dfrac{1}{1 - \dfrac{Q_{L}}{Q_{H}}} = \dfrac{1}{1 - \dfrac{T_{L}}{T_{H}}}

Given, T_{L} = 460 K and T_{H} = 540 K. So,  the minimum work per unit heat transfer is given by

\dfrac{W_{in}}{Q_{H}} = \dfrac{T_{H} - T_{L}}{T_{H}} = \dfrac{540 - 460}{540} = 0.15
