We know our diameter is 1.2cm so our radius is 0.6 cm or 0.006 m. Now we find our volume flow rate, Q. so 155l/8min * 1min/60s *1m^3/1000L = 3.2292*10^-4 m^3/s.
Velocity= Volume flow rate/Area
V=Q/A
V= 3.2292*10^-4 m^3/s
Water flows through a 1.2 cm diameter pipe into a 155 L bathtub, which it fills in 8 min.What is the speed of the water in the pipe?

sorry. here is complete answer.

V= 3.2292*10^-4 m^3/s/ pie*((6*10^-3)^2)
V=2.8 m/s
