Air enters a compressor at a pressure of 74.7 kPa and 287 K and leaves at 622 kPa and 579 K. The air flow rate is 50 kg/s. Calcu
late the shaft power input required to drive the compressor. Hint: The shaft power that goes into the compressor increases the total enthalpy of the air from the inlet to the exit, since there is no heat into the system.

Answer:
51.4 Ohms
Explanation:
By applying voltage division rule
where v is voltage, subscripts i and f represnt initial and final, R is resistance, m is internal and l is external.Substituting 7V for final voltage, 10V for initial voltage and the external resistance as 120 Ohms then
