Which of the following holds true for Prandtl Number? a. As the velocity boundary layer thickness increases, the Pr increases. b. As the thermal boundary layer thickness decreases, the Pr increases. The ratio of the velocity and thermal boundary layer thickness determines the Pr. d. More than one response. С. e. None of these. е. For a 5-zone enclosure, if F12 = 0.25, F13 = 0.50, F14 = 0.10, then The sum of all the view factors of F1j is 1. b. F11 + F51 = 0.15 F11 + F51 = F12 - F14 d. More than one response. %3D а. С. е. None of these. Which method(s) can be used to solve for the view factor between two 2D objects? Yamauti Principle а. b. Hottel's Crossed String Method c. Siegel and Howell's Equation d. Unit Sphere Method e. More than one response. Which of the following holds true for Prandtl Number? a. As the velocity boundary layer thickness increases, the Pr increases. b.
