Question
4.2 AMVA turbo-alternator is working on full
load at power factor of 0.9 and efficiency of
28%. find the quality of cooling air required
per minute at full load, assuming that 0% of
the total losses are dissipated by internally
circulating air the inlet air temperature is
12°C and the temperature rises to 28 C
given that the specific heat of air is 1.243
and that of air at 1kg occupies 0.8 m³
