## Homework Statement

Given:

Water flows through a 15.24m long, 1.6cm diameter hose.

pressure at the outdoor tap = 275.8kPa

volumetric flowrate, Q = 7.5e-4 m^3/s (i.e. 7.5L for 10 seconds)

viscosity of water, μ = 0.001 Pa*s

density of water, ρ = 1000 kg/m^3

Look for: the roughness of the hose

## Homework Equations

Renolds number:

Darcy equation:

Moody chart:

## The Attempt at a Solution

I have calculated Renolds number = 7958 ==> turbulent flow

I used Darcy equation and found out the friction factor, f, is great than 1.

I am confused and stuck here.

I must have used the wrong formula or missed some important steps.

Please help me by providing some advice, double checking my work or giving some steps would be greatly appreciated!
