Pull Forces - Angles

We have a system where we are pulling a hose on some rails, but are struggling to find the perfect angle to have the rails.

I thought I should be able to work out the best angle mathematically before buying initial metal work prototypes.

How would you go about finding the resultant force that it takes to pull the hose as it travels down the rail?

Why does the hose travel down the rail?

Drum, Retraction, Carriage

Few reasons the hose actually goes thru a carriage, this carriage is attached to a spring drum that retracts the hose when the user lets go, or it aids them.

So what i am trying to work out is the best angle of the rails to provide as little friction or resistance to the hose system.
