Answer:
Yes, it can can be completed adiabatically
Explanation:
To solve the problem we will resort to the theory of thermodynamics,
It is necessary to develop this problem to resort to the A-11E tables in English Units for R134a (since the problem requires it, if it were SI just to change to that table)
State 1 indicates that the refrigerant is at 60 ° F,
In the first table (attached image of the value taken) the value of the entropy is
For State 2 the refrigerant is at 50% quality and at a pressure of
In table 2 of the refrigerant (for the pressure values) we perform the reading and we have to
We know that,
The change in enthalpy would be given by
<em>The change in enthalpy is positive, so the process can be completed adiabatically</em>
This is due to water pressure
Answer:
Explanation:
Given that,
The peak wavelength is
λp = 475nm
Then, we want to find the temperature,
From Wein's displacement law,
When the maximum is evaluated from the Planck radiation formula, the product of the peak wavelength and the temperature is found to be a constant (k = 2.898 ×10^-3 mK)
So, applying this we have
λp•T = 2.898 ×10^-3
T = 2.898 × 10^-3 / λp
T = 2.898 × 10^-3 / 475 × 10^-9
T = 6101.05 K
Answer:
both
