Consider airflow over a flat plate of length L=1 m under conditions for which transition occurs at Xc = .5 m based on the critical Reynolds number, Rex, c = 5 x 105 .A). Evaluating the thermophysical properties of air at 350K, determine the air velocity. B). In the laminar and turbulant regions, the local convection coefficients are, respectively, hlam (x) = Clam x-.5 and hturb = Cturb x-.2where at, T= 350K, Clam = 8.845 W/m3/2 K, Cturb = 49.75 W/m1.8 K, and x has units of m. Develop an expression for the average convection coefficient, hlam (x), as a function of distance from the leading edge x, for the laminar region, o

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
