Question #152583

Water flows through a pipe of varying cylindrical cross-section. The speed of the water is 4m/s when the pipe radius 3cm. What is the speed of water through a cross-section of 6cm radius?

Expert's answer

"A_1v_1=A_2v_2\\\\\\pi r_1^2v_1=\\pi r_2^2v_2\\\\3^2(4)=6^2v_2\\\\v_2=1\\frac{m}{s}"
