Air is compressed from 1 bar and 27c (state 1) to 2.1 bar (state 2) in an axial flow compressor. work required for the compression process is 94.6 kj/kg. heat transfer of 14 kj/kg occurs from the compressor to the surroundings at an average surface temperature of 40c. assume that the surrounding pressure is 1 bar and temperature is 20c. consider variable specific heats for air. molecular weight of air = 28.97 kg/kmol. (a) calculate temperature (k) of air at the compressor exit. (b) find the exergy destroyed (kj/kg) during the compression process using entropy generation. (c) perform an exergy accounting of the compressor. answers: (a) 380 k; (b) 20.5 kj/kg

half of a circle

explanation:

the arrow and the top of the circle is matching together. it is not a polygon because a polygon would always be the same shape. therefore, an half of a circle is called semicircle so you would find the radius of it.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
