If I have a 1" pipe, that is 1 foot long, that can hold .04 gallons of water, how fast is the water flowing at feet per second if water is flowing at 50 gallons per minute?

Schedule 40 Pipe, Inside Diameter = 1.049 inches
Area = (1.049/2)^2 x PI = 0.864 in^2 / 144 = 0.006 ft^2
50 gal/min / 7.48 gal/ft^3 = 6.68 ft^3/min / 60 = 0.111 ft^3/sec
Flow Rate = Area x Velocity so Velocity = Flow/Area
Velocity = 0.111 ft^3/s / 0.006 ft^2 = 18.5 ft/sec

Q=V x A
Q= Discharge
V= Average Velocity
A= Cross sectional area of pipe

50 gal/min = 5/6 gal/sec, or is 5/6 / 0.04 pipefuls per second. As the pipe is 1ft long the water speed is just 5/6 / 0.04 = 20.833... ft/sec.

V = C*(h*D/(L+54*D))**1/2
In which V = Approx. mean velocity in feet per sec
C = Friction coefficient from table
D = Dia. of pipe in feet
h = Total head in feet
L = Total length of pipe in feet
