Question
A turbulent boundary layer is desired for better mass transport into a catalytic surface placed
inside a pipe with ID = 12 cm. The catalyst is expensive, so it is only placed at a distance x
from the cylindrical pipe entrance. Air (p = 1.3 kg/m³ and µ 1.5 x 105 kg/m's) is flowing
with an approximate core fluid velocity, Vxx, of 10.5 m/s.

Catalyst-coated pipe
a) Determine the distance x (in m) to achieve a turbulent boundary layer and the thickness
of the boundary layer (8 in m) at this distance x, assuming a developed turbulent
boundary layer.
b) Determine the total volumetric flow (Q in m³/s), assuming Vx∞ = 10.5 m/s at distance x.
Assume, at this point, the boundary layer is turbulent and follows the profile
31/7 = (²)²/7.
