Fluid dynamics problem?

Question

a pipe carries oil at a mean velocity of 6m/s. the pipe is 5km long and 1.5 diameter. the surface roughness is 0.8mm. the density is 890kg/m^3 and the dynamic viscocity is 0.014 Ns/m^2.

Determine: 1) the friction coefficient using the moody chart or haalands formula

2) the friction head, hf

any help would be greatly appreciated.

Answer 1

To find the friction coefficient, calculate the Reynolds Number and the Relative Roughness then go to the Moody Chart

For the Friction Head, use the Darcy Weisbach Equation  

Since this is a homework problem, really dont want to give any more help, but if needed, just ask.

Answer 2

dang son! dunno the answer but i'm taking that course next semester with other 4 more engineering class..and i'm freaking scared!!!
