## Homework Statement

A fluid with relative density σ=0.7 and kinematic viscosity [tex]\nu[/tex]=0.6mm

^{2}/s is used as a cooling agent in an electrical

equipment cooling system. The fluid circulates in a 2m long copper pipe of 3mm in diameter. A pump is used to

create a head difference of 0.5m between entry and exit of the system. Use results of your small pipe experiment to

calculate coolant flow rate through the system. Justify application of your results to this problem.

From the small pipe experiment I was able to find Reynold's number and the friction factor.

## Homework Equations

h

_{f}=f * L/D * v

^{2}/2g

f = 16/Re

Re= Q * d / [tex]\nu[/tex] * (d

^{2}*pi/4)

## The Attempt at a Solution

From the small pipe experiment I was able to find Reynold's number and the friction factor. However, since the pipe from the actual problem is not sure I am not sure how Reynold's number will correlate between the two pipes to help find the flow rate.

Hopefully this was clear.
