What is the relationship between the friction factor and Reynolds number in heat exchange?

I did a lab experiment on a heat exchanger and the graph of friction factor against reynolds number had a positive gradient contrary to what I expected from the relationship f=0.046/Re^0.2. What could be the reason for this?
