Water flows under pressure from one pipe into a second pipe having half the diameter. The volume flow rate in the narrow pipe is ________ that in the wide pipe, and the speed of the water in the narrow pipe is _______ that in the wide pipe

• Physics -

Q = u A = constant

The volume flow rate in the narrow pipe is ___ the same as_____ that in the wide pipe, and the speed of the water in the narrow pipe is ___4 times____ that in the wide pipe

pi R^2 = 4 pi(R/2)^2

• Physics -

flow rate in narrow tube is 16times less than in wide tube. speed in narrow tube will be 4time smaller than wide tube
