Chapter 25, Problem 63PE

Referring to the electric room heater considered in the first example in this section, calculate the intensity of IR radiation in W/m2 projected by the concave mirror on a person 3.00 m away. Assume that the healing element radiates 1500 W and has an area of 100 cm2, and that half of the radiated power is reflected and focused by the mirror.

Consider a room heater that uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 49.0 cm and produces an image of the coils 3.10 m away from the mirror. Calculate the intensity of IR radiation in W/m2 projected by the concave mirror on a person 3.10 m away. Assume that the heating element radiates 1,350 W and has an area of 130 cm2, and that half of the radiated power is reflected and focused by the mirror.
A room heater uses a concave mirror to reflect infrared radiation from hot coils. The mirror has a radius of curvature of 55.0 cm and produces an image of the coils 3.40 m away from the mirror. What is the intensity of IR radiation in W/m2 projected by the concave mirror on a person 3.40 m away? The heating element radiates 1,750 W and has an area of 130 cm2, and half of the radiated power is reflected and focused by the mirror.
Two infinitely long parallel plates of width w are located at w distance apart,. The two plates behave as black surfaces, where surface 1 has a temperature of 500°C and surface 2 has a temperature of 50°C. Determine the radiation heat flux between the two surfaces.
