In an experiment, the local heat transfer over a flat plate were correlated in the form of local nusselt number as expressed by the correlation nux=0.035rex^(0.8) pr^(1/3) determine the ratio of the average convection heat transfer coefficient (h) over the entire plate length to the local convection heat transfer coefficient (hx) (h/hx = l) at x = l.

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:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
