Two pipes of lengths 2500 m each and diameters 80 cm and 60 cm respectively, are connected in parallel. The coefficient of friction for each pipe is 0.006 and the total flow is 250 litres/s. The rates of flow in the pipes are nearly

• A. 0.17 m3/s and 0.1 m3/s
• B. 0.23 m3/s and 0.1 m3/s
• C. 0.17 m3/s and 0.4 m3/s
• D. 0.23 m3/s and 0.4 m3/s
