  • Question 1
    1 / -0

    Bodies A and B have thermal emissivity of 0.01 and 0.81 respectively. The outer surface areas of the two bodies are same. The two bodies emit total radiant power at the same rate. Find the temperature of B if the temperature of A is 5802 K.

  • Question 2
    1 / -0

    It is observed that intensity of radiation is maximum in case of solar radiation at a wavelength of 0.49 microns. Assuming the sun as a black body, its emissive power is ___________ × 107 W/m2

    Wein displacement constant = 0.289 × 10-2 mK.

    Stefan – Boltzmann constant, σ = 5.67 × 10-8 W/m2K4

  • Question 3
    1 / -0

    Two infinite parallel plates with 7 radiation shields are held close together and are maintained at 1200 K and 800 K respectively. The plates and shields have an emissivity of 0.66. If 5 more shields are now inserted between them, then calculate the percentage change in heat transfer _______
