Air is compressed in an axial-flow compressor operating at steady state from 27โˆ˜C, 1 bar to a pressure of 2.1 bar. The work required is 94.6 kJ per kg of air flowing. Heat transfer from the compressor occurs at an average surface temperature of 40โˆ˜C at the rate of 14 kJ per kg of air flowing. The effects of motion and gravity can be ignored. Let T0=20โˆ˜C, p0=1 bar. Assuming ideal gas behavior.(a) determine the temperature of the air at the exit, in โˆ˜C(b) determine the rate of exergy destruction within the compressor, in kJ per kg of air flowing, and (c) perform a full exergy accounting, in kJ per kg of air flowing, based on work input

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ยบc. note that this calculation is only approximate because ocean warming is not uniform with depth.
