A certain pump is able to maintain a pressure difference per unit length in a cylindrical pipe of radius R 1 and deliver a mass flux Q 0 . It is desired to replace the single pipe with two smaller cylindrical pipes each of radius R 2 . The pump will maintain the original pressure difference per unit length in each pipe, and the total mass flux through the two pipes re-mains equal to Q 0 . What is the ratio R 1 /R 2 ?
