Design a J-Type thermocouple system were 130°C produces 8 V. Use an RTD sensor to compensate the reference temperature. At T- 50°C RTD= 140 ohm and a=0.005, neglect self-heating, Assume that the reference temperature changes from 0° to 50°C.

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?
