MODERATOR NOTE: THERE IS NO TEMPLATE BECAUSE THIS THREAD WAS ORIGINALLY MISPLACED IN A NON-HOMEWORK FORUM Viscous liquid (ρ = 1460 kg/m3, μ = 5.2×10−1Ns/m2) is pumped through a smooth pipe with a 0.1 m diameter, at a rate of 5×10−2m3/s. Using your Fanning friction factor versus Reynolds Number plot to estimate the driving force needed to maintain the flow rate mentioned earlier. I need to express the driving force in terms of pressure drop per unit length of the pipe. No length is provided so the force will be a function of pressure drop and a constant of L. I've found the the velocity, reynolds number. The fanning friction factor I got was by reading of the subsequent friction factor for the calculated reynolds number from the plot. I'm not sure where to go from here as I've used the darcy-weisbach pressure loss equation but don't know to solve the equation with varying units. Could someone guide me as to what to whether i've taken the correct approach and how I should go about solving the equation? Thank you so very much.
