Problem #3 Air flows over a flat plate at 4 m/s. An approximation for the x component of velocity in the in- compressible laminar boundary layer is a sinusoidal variation from u-0 at the surface (y-0) to the freestream velocity, U, at the boundary-layer edge (y-5). The equation for the profile is u-Usin( %), where cVx and c is a constant. The boundary layer is 9 mm thick 1 m from the edge of the plate. (a) Predict the boundary-layer...

Air at T=25°C and pressure P=1 bar flows over a square plate with a velocity V=1 m/s. This plate has a length L= 1 m and it is heated over its entire length; the plate temperature is constant Tp=100°C. The following data are given. For air: dynamic viscosity: mu = 1.9*10–5 kg/(m.s); density: rho = 1.05 kg/m3; conductivity k = 0.03 W/(m K); Specific heat Cp = 1.007 kJ/(kg K); Prandtl number Pr = 0.7 For laminar flow over a...

Air at a temperature of 300 K flows over one side of a flat plate of width 1 m at a velocity of 20 m/s. The plate has a constant surface temperature of 350 K. Assume Re(x,c)=5x10^5. a) What is the velocity boundary layer thickness at the end of the plate if L=0.25 m? What if L=1 m? b) Calculate the drag on the plate if L=0.25 m. What is the drag if L=1 m? c) Find the heat transfer...

Start by checking your Reynolds number (Re) at the end of the
plate, where it will be at a maximum. This will determine if your
boundary layer is simply laminar along the length of the plate or
if it becomes turbulent (the "mixed BL" condition). Once you know
the conditions of the flow, you can solve for the velocity BL
thickness directly with an equation from the list of external flow
correlations (posted). Your properties should be looked up at...
