Q. For a laminar flow of a liquid metal over a flat plate, the thicknesses of the velocity and thermal boundary layers are \ud835\udeff\ud835\udc63 and \ud835\udeff\ud835\udc61 respectively. Kinematic viscosity (viscosity\/density) of liquid metal is significantly lower than its thermal diffusivity [thermal conductivity \/ (density \u00d7 specific heat)]. Based on this information, pick the correct option.<\/p>\n\n\n\n
(Note: The temperature of the liquid metal is different from that of the plate).<\/p>\n\n\n\n
(A) \ud835\udeff\ud835\udc63 < \ud835\udeff\ud835\udc61 (B) \ud835\udeff\ud835\udc63 > \ud835\udeff\ud835\udc61<\/p>\n\n\n\n
(C) \ud835\udeff\ud835\udc63 = \ud835\udeff\ud835\udc61 (D) Information insufficient<\/p>\n\n\n\n
