Water at 20C is flowing at steady-state through a piping system as shown. 1 The velocity distribution (in m/s ) in a pipe with D: = 4 cm is given by 1/7 Ug = 31 3(1-)" where R = D/2 and r is the radial coordinate. If the volumetric flow rate of water through a pipe with D3 = 1 cm is 0.072 m/min, calculate the volumetric flow rate of water (in cm/s) through a nine with Phi 2 cm
