Air enters a compressor with a pressure of 14.7 lbf/in.2 , a temperature of 70F, and a volumetric flow rate of 40 ft3 /s. Air ex
its the compressor at 50 lbf/in.2 and 190F. Heat transfer from the compressor to its surroundings occurs at a rate of 20.5 Btu per lb of air flowing. Determine the compressor power, in hp, for steady-state operation.

Answer:
<h3>The area of second coil is ≅ 0.025Explanation:
Given :
No. of turns in the first coil
No. of turns in the second coil
Area of first coil
According to the law of electromagnetic induction,
Induced emf =
Where magnetic flux.
Since given in question emf of both coil is same so we compare above equation.
Therefore, the area of second coil is ≅ 0.025
