I need to answer the following question: assume you have two pipelines, one with diameter d and another with diameter D (where d << D). In both flows the same fluid with the same average velocity, but, in one Bernoulli's principle holds much better than the other. Which pipeline is this one and why (with proof)? (Help: check the assumption of Bernoulli's theorem at a differential level).
Homework Answers
Bernoulli's equation will be more suitable for large
diameter pipes.
Explanation:
We know that the loss due to friction which is major loss
is inversely proportional to the diameter for a given average flow
velocity. In Bernoulli's assumption losses are not considered so it
should hold better for large pipe diameters.

SECTION A Petroleum distilate is pumped from one large diameter tank to another higher tank, via a pumping station in an oil refinery. The petroleum is pumped at a speed of 2 ms through a 150 m long pipeline of 100 mm internal diameter. The vertical distance pumped is 20 m. The sum of the entry, exit and other component losses is equivalent to 5 times the velocity head, Table Q1 Fluid density Friction factor f for the...

this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
