The federal new source performance standards for a new coal‐fired power plants require that emission of nitrogen oxides be less than 0.7lb of nitrogen oxides per million BTU of coal burned. If a plant emits 0.45lb of NO and 0.15 lb of NO2 per million BTU, what is its nitrogen oxide emission reported as?

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

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?

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
