Does decreasing pipe diameter increase pressure?

In water flowing pipeline, pipe size and water pressure are dependent on each other. Because if the diameter of a pipe decreased, then the pressure in the pipeline will increase. As per Bernoulli's theorem, pressure can be reduced when the area of conveyance is reduced.

Does a smaller hose increase water pressure?

In general, a smaller hose will increase the water pressure. The smaller the pipe, the more resistance the water will see. A 3/4″ hose will see a decrease of around 2 PSI per 100 ft. A 5/8″ hose will see a 4 PSI decrease.
