A hot tub is to have 40 outlets that are each 8 mm in diameter with water
Question:
A hot tub is to have 40 outlets that are each 8 mm in diameter with water exiting at 7 m/s. Treating each of the outlets as if they are at the surface of the water and exit into atmospheric pressure, would a ½ HP pump be adequate? If so, what is the minimum efficiency that will still provide adequate power with this selection?
