Question

To a good approximation, the dynamic viscosity u, the thermal conductivity k, and the specific heat c, are independent of pressure.In what manner do the kinematic viscosity v and thermal

diffusivity a vary with pressure for an ideal gas? Determine a of air at 350 K for various pressures. Assuming a transition Reynolds number of 1 x 105, determine the distance from the leading edge of a flat plate at which transition will occur for air at 350 K at various pressures with u =2 m/s. What is the viscosity of air at 350 K, 1 atm, in N-s/m^2? u = _______N-s/m2
