Consider air entering an ADIABATIC chamber at a rate of 100 lbm/s at 1 atm and 70°F (note non-absolute temperature scale). The air leaves this chamber at 20 atm. Suppose that the kinetic energy in the flow stream is negligible (i. e. u1 ≈ u2 ≈ 0). Determine: (a) exit temperature T2 and specify whether this is a minimum or a maximum temperature value and (b) amount of horsepower associated with this process and specify whether it is input or output.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

It equals just about 6,300 km per hour each day an week
