velocity boundary layer

6.36   For laminar boundary layer flow over a flat plate with air at 20°C and 1 atm, the thermal boundary layer thickness 8t is approximately 13% larger than the velocity  boundary  layer   thickness   8.   Determine the ratio 8/8t if the fluid is ethylene glycol under the same flow conditions.

6.37   Sketch the variation of the velocity and thermal bound- ary layer thicknesses with distance from the leading edge of a flat plate for the laminar flow of air, water, engine oil, and mercury. For each case assume a mean fluid temperature of 300 K.

6.38   Consider parallel flow over a flat plate for air at 300 K and engine oil at 380 K. The free stream velocity is uoo = 2 m/s. The temperature difference between the surface and the free stream is the same in both cases, with Ts > Too.

(a)    Determine the location where transition to turbu- lence occurs, xc, for both fluids.

(b)   For laminar flow over a flat plate, the velocity boundary layer thickness is given by

Calculate and plot the velocity boundary layer thickness 8 over the range 0 x xc for each fluid.

Estimate the surface temperature of the chip if it is dis- sipating 30 mW.
