Answer:
Ratio of magnetic field will be 
Explanation:
We have given radius of the loop r = 30 mm = 0.03 m
We know that magnetic field at the center of the loop is given by
---------eqn 1
Number of turns in the solenoid is given as n = 3 turn per mm = 3000 turn per meter
We know that magnetic field due to solenoid is given by
-------------eqn 2
Now dividing eqn 1 by eqn 2

Answer:
= 287kW
Explanation:
Knowing the enthalpy data, we have to

So,

Here,
m=mass flow rate
h= Enthalpy of refrigerant at the compressor
Replacing
= 1.2 × 239.16
= 287kW
