2. Air enters the compressor of an ideal air-standard Brayton cycle at 100 kPa, 300 K, with a volumetric flow rate of 5.2 m3 /s. The turbine inlet temperature is 1400 K. For compressor pressure ratios of 6, 8, and 12, determine (a) the thermal efficiency of the cycle, (b) the back work ratio, (c) the net power developed, in kW.

What precautions should you take to prevent injuries when dealing with heavy loads?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
