4) For a smooth pipe flow of water with Re = 20,000, the friction factor was found to be f = 0.026 (from Moody chart). If the pipe is replaced with a pipe twice the diameter, keeping the same flow rate and conditions, what is the friction factor for the new pipe? a. f= 0.022 b. f= 0.028 c. f= 0.039 d. f= 0.052

Question 4 a) Derive the Rigid Column Theory of unsteady fluid flow analysis in pipelines. 10 marks b) A 1.75km horizontal pipe, 0.9m in diameter, is supplied by a constant-head tank. The water level in the tank is 15 m above the discharge point of the pipe. The pipe discharges directly into the atmosphere, with the flow controlled by a valve at its end. i. Calculate the pressure rise at the valve for a rigid water column if the...

just now i sent this questions.
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
the heat transfer coefficient, h. please help me. thank you.
this pic is a note on constant surface temperature.
