Water flows into your home through a circular pipe (A) at height hA. Pipe A has an internal radius r1, flow speed v1, and absolute pressure P1. Pipe A connects to a smaller circular pipe B which is located on an upper floor, above pipe A at a height hB. Pipe B has an internal radius rB that brings water to a sink. hA = 0.0 m r1 = 0.100 m v1 = 1.51 m/s P1 = 4.0 x 105 Pa hB = 5.00 m rB = 0.0500 m water = 1000. kg/m3 Find the mass flow rate in pipe B
