Unformatted text preview: Click to edit Master subtitle style Radiation Exchange Between Surfaces: Chapter 13 Section 13.2 The gage has a black surface that is 10mm in diameter and is maintained at 17oC by the cooling water. The heater, 200 mm in diameter, has a black surface that is maintained at 800 K. The surroundings and the air are at 27oC and the convection heat transfer coefficient is 15 W/m2-K. Plan: a) Governing equation. b) Find view factor. c) Find area. d) Solve for q. e) Solve for net radiation to the gage. The gage has a black surface that is 10 mm in diameter and is maintained at 17oC by the cooling water. The heater, 200 mm in diameter, has a black surface that is maintained at 800 K. The surroundings and the air are at 27oC and the convection heat transfer coefficient is 15 W/m2-K. Find the net radiation exchange between the heater and the gage. Governing equation: qh-g = AhFhg(Jh – Jg) qh-g = AgFgh σ(T h4 – Tg4) The gage has a black surface that is 10 mm in diameter and is maintained at 17oC by the cooling water.
