Question 1125506
Water travels at 10' per second through a 2" pipe with inside diameter of 2.067". Determine amt.(gals.)the pipe delivers per hr. 
10' per sec. = 36000' per hr. 
:
Think of it as a cylinder of water with 2.067" diameter and 36000 ft long.
Find it's volume in cubic ft
Find the radius in ft: {{{2.067/(2*12)}}} = .086125 ft is the radius
V = {{{pi*.086125^2*36000}}}
V = 838.9 cu/ft
Convert to gallons 1 cu/ft = 7.481 gal 
V = 838.9 * 7.481 
V = 6,275.82 gallons in 1 hr
