Air at 1 atm and 20°c is flowing over the top surface of a 0.2 m 3 0.5 m-thin metal foil. the air stream velocity is 100 m/s and the metal foil is heated electrically with a uniform heat flux of 6100 w/m2. if the friction force on the metal foil surface is 0.3 n, determine the surface temperature of the metal foil. evaluate the fluid properties at 100°c.
Answers: 2
is the surface temperature and T_{\infty }[/tex] is ambient temperature
