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.

Wavelength of 125 meters is moving at a speed of 10 m/s. what is it's frequency?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.

If jason ii needs 15 kw of power at 300 volts to operate, what amperage of current must flow through the cable?
