The gauge pressure of a pneumatic cylinder reads 40 lb/in^2 when the volume is 15 in^3. The cylinder is compressed until the gauge reads 50 lb/in^2. Assume standard atmospheric pressure (14.7 psi). Sketch and label all known and unknown values in your Engineering Notebook

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?
