Answer:

Explanation:
Given that

We know that
Rex=ρvx/μ
So


All other quantities are constant only x is a variable in the above equation .so lets take all other quantities as a constant C

We also know that
Nux=hx/K

m is the constant

This is local heat transfer coefficient
The average value of h given as


---------1
The value of local heat transfer coefficient at x=L

-----------2
From 1 and 2 we can say that

Answer:
(a) 2.5 ksi
(b) 0.1075 in
Explanation:
(a)

Making
the subject then

where
is the stress and
is the strain
Since strain is given as 0.025% of the length then strain is 
Now substituting E for
then

(b)
Stress,
making A the subject then


where d is the diameter and subscripts o and i denote outer and inner respectively.
We know that
where t is thickness
Now substituting



But the outer diameter is given as 2 in hence



As already mentioned,
