Question

Consider a cylindrical furnace of 5 m5\text{ m} diameter and 5 m5\text{ m} length with bottom, top and curved surfaces maintained at uniform temperatures of 800 K800\text{ K}, 1500 K1500\text{ K} and 500 K500\text{ K}, respectively. The view factor between the bottom and top surfaces, F12F_{12} is 0.20.2. The magnitude of net radiation heat transfer rate between the bottom surface and the curved surface is _____________ kW\text{kW} (rounded off to 1 decimal place).
A cylindrical furnace with top surface (2) at 1500 K, bottom surface (1) at 800 K, and curved surface (3) at 500 K.
All surfaces of the furnace can be assumed as black.
The Stefan-Boltzmann constant, σ=5.67×10−8 W m−2 K−4\sigma = 5.67 \times 10^{-8}\text{ W m}^{-2}\text{ K}^{-4}.
