Sure, unless the cost prohibits it. Typically digging the trench is the big cost and the pipe cost difference is minimal.
From a firefighter who taught hydraulics for decades to pump operators, the above by ultrarunner is an excellent post. I would add to this the friction loss at various velocities through the pipe:
PVC Pipes - Friction Loss and Flow Velocities Schedule 4
PVC - Friction Loss in Fittings and Equivalent Length

But what's the flow at the nozzle and the reaction force? :thumbsup:
For a total of 180 feet, you really wont see any difference by increasing your pipes size to one inch. I would run 3/4 in schedule 40 white PVC in 20 foot lengths with the bell attached to one end. I would use purple primer and clear heavy duty cement.
For a little bit of water to keep some flowers alive, I ran 3/4 inch 800 feet to my front gate. It's flat, so that helps, and there is some loss in pressure, but when I turn on the spicket, water shoots out of it with plenty of pressure to run a sprinkler.
If you where wanting to go that for for a home of some kind, then going bigger in pipe would make a lot of sense. I just don't see it for 180 feet.
If you were wanting to pump 250 GPM through 200' of 1" pipe then you would need to pump about 1,875 PSI for the FL + NP of 100 PSI (assuming we are using a combination nozzle) gives us roughly 2,000 PSI EP.
If we were using a smooth bore nozzle at say 60 PSI it may be more realistic to do as the EP would be less than 2,000 PSI.
The reaction force depends on if the chief sees you trying this.
