Data that have to be used for solving the practical examples and the problems: Atmospheric pressure for all problems and practical examples is B = 946 mbar. For all practical examples and problems consider air as ideal and perfect gas. Universal gas constant R₁ = 8314.472 J/(kmol.K). Air ideal gas constant R = 287 J/(kg.K). Atomic weights in kg/kmol: Carbon - 12.0107; Nitrogen - 14.0067; Oxygen - 15.9994. Isentropic exponent: k=1.67 for monatomic gases; k=1.40 for diatomic gases; k=1.29 for polyatomic gases. Wien's displacement constant: b=0.0028977685 m.K. Stefan-Boltzmann constant: σ = 5.6704-108 W/(m²K) Standard state conditions: P=101325 Pa, T.-273.15 K. and its outer surface PE 5 What wavelength (in nanometers) is the peak intensity of the light coming from a star whose surface temperature is 9639 Kelvin? Calculate total energy radiated per unit area by a black body at this temperature.
