To a good approximation the dynamic viscosity μ, the thermal conductivity k, and the specific heat c p are independent of pressure. In what manner do the kinematic viscosity v and thermal diffusivity a vary with pressure for an incompressible liquid and an ideal gas? Determine a of air at 350 K for pressures of 1, 5, and 10 atm. Assuming a transition Reynolds number of 5 x 105, determine the distance from the leading edge of a flat plate at which transition will occur for air at 350 K at pressures of 1, 5, and 10 atm with u∞ = 2 m/s.
