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?

The speed of the water in the pipe can be determined by the volume of water passing through the pipe over time. The volume of water flowing through the pipe in 8 minutes can be calculated by multiplying the cross-sectional area of the pipe (πr2) by the length of the pipe in 8 minutes. Speed = (π x 0.062 cm2 x 155 L) / (480 sec) Speed = 0.25 cm/sec
