Dear Senior's

I am a Final year Mechanical Engineer. i am facing problem for calculating Pressure drop of a helical coil pipe line (in subject Power plant Engineering).
I went through net in this regard and found nothing useful. only got how to calculate length of pipe required etc is there any direct relation to calculate the pressure drop in the coil coz i think there will be more of losses as as the flow direction is changing........ So the pressure drop will be more as compared to stright pipe line.!!!

Any help please

Hi ,

f(coil) = f (straight pipe) *(1+3.5*(d/D))

f = Moody friction factor
d =inside diameter of the coil tubing
D= Diameter of the helical coil

Reference Matthew J.Realff & Jde T sommerfield
(Georgia insitute of technology)

hope this helps
