Lecture 44 (2014) Solar radiation 6 of 7

This lecture continues with radiation but the focus shifts to atmospheric and solar radiation. The properties of the sun are considered and the surface temperature of the sun is calculated using the solar constant. The spectral distribution of the solar radiation on the ground is considered as well as the scattering in the atmosphere (diffuse radiation). A few simple solar radiation problem are addressed. The lecture was based on the textbook of Cengel and Ghajar (4th edition) and was presented as part of a heat transfer class to the fourth year students of the Department of Mechanical and Aeronautical Engineering by Prof Josua Meyer, Head of the Department of Mechanical and Aeronautical Engineering of the University of Pretoria, South Africa. Lecture was presented on 19 September 2014.
