Where did you get this formula from? How did you wind up to this product rule?
I got u'(x) = (2/3) x^(-1/3)
u''(x) = (-2/9) x^(-4/3)
v'(x) = -(1/3) < (6-x)^(-2/3) >
v''(x) = -(2/9) < (6-x)^(-5/3) >
using your formula it's difficult to simplify after this step
< (-2/9) (x^(-4/3))...

How do I find the second derivative of the function:
f(x)= x^(2/3) (6-x)^(1/3)
I have found the first derivative and checked my solution:
′()= 4− / ^(1/3) (6−)^(2/3)
The final solution is supposed to be:
''()= -8 / ^(4/3) (6−)^(5/3)
I know almost all the steps but I couldn't...

A horizontal layer of soil in a tube 100 x 100 mm in cross-section. water is supplied to maintain a constant head difference of 300 mm across the sample. the coefficient of permeability of the soils in the direction of flow through them are as follows:
Soil A = 10^-2...
So for the first question, do I ignore what it says about radiation & convection?
For the second it's a flat plate... I've just asked my instructor via e-mail & he said that Reynold's number has to be above 10^5 to expect turbulet flow.
I appreciate your help, thank you!
The equation comes from Fourir's law for convection.
K is the thermal conductivity (kW/mK) r2 is the outer radius (m) & r1 is the inner radius (m)...
Sorry for the typing mistake: Q = 2 Pai K L (T1 - T2) / ln (r2 / r1)
The second equation is Reynold's Number.
