You need to extend a 2.20 inch diameter pipe, but you have only a 1.00 inch diameter pipe on hand. You make a fitting to connect these pipes end to end.
If the water is flowing at 9.00 cm/s in the wide pipe, how fast will it be flowing through the narrow one?
I need to find the velocity in cm/s. Thanks!!

"continuity equation":
flow rate in = flow rate out
A1 v1 = A2 v2
substitute pi*r^2 for each of the areas and solve for v2
v2 = (r1/r2)^2 v1
flow rate in = flow rate out
A1 v1 = A2 v2
substitute pi*r^2 for each of the areas and solve for v2
v2 = (r1/r2)^2 v1

(2.2^2 x 9)/(1^2) = 43.56cm/sec.
Or, (2.2^2/1^2) x 9 = 43.56cm/sec.
