Answer:
The claim is valid.
Explanation:
Let assume that heat pump is reversible. The coefficient of performance for the heat pump is:
![COP_{HP} = \frac{T_{H}}{T_{H}-T_{L}}](https://tex.z-dn.net/?f=COP_%7BHP%7D%20%3D%20%5Cfrac%7BT_%7BH%7D%7D%7BT_%7BH%7D-T_%7BL%7D%7D)
![COP_{HP} = \frac{300\,K}{300\,K-260\,K}](https://tex.z-dn.net/?f=COP_%7BHP%7D%20%3D%20%5Cfrac%7B300%5C%2CK%7D%7B300%5C%2CK-260%5C%2CK%7D)
![COP_{HP} = 7.5](https://tex.z-dn.net/?f=COP_%7BHP%7D%20%3D%207.5)
The claim is valid as real heat pumps have lower coefficients of performance.
Answer:
This filter can either be Band Pass or Band
Answer:
Explanation:
The deatailed diagram of VCRS is given below such
1-2=Isentropic compression in which temperature increases at constant entropy
2-3=Isobaric heat rejection i.e. heat rejected at constant pressure(condensation)
3-4=Irreversible expansion or throttling in which enthalpy remains constant
4-1=Isobaric heat addition(Evaporation)
Answer:
The power input to the pump is 292KW
Explanation:
In this question, we are asked to calculate the power input to a pump neglecting potential and kinetic energy changes.
