Answer:
attached below
Explanation:
<u>To derive the equation we have to make some assumptions </u>
assumptions:
Assume T depends on Z alone
Assume uniform thermal and electrical conductivities (k and ke) in the wire, Assume a uniform heat
transfer coefficient h from the wire to the air stream.
attached below is the required derivation of the equation
Answer:
Check the explanation
Explanation:
First of all the initial or primary and final masses can be calculated with the use of the ideal gas relations.
The net It transfer is determined from the energy balance. The initial and final internal energies and the enthalpy of the air in the supply line are obtained from A-I] for the given temperatures.
