(a) A 50-acre urban watershed in the Minnesota has a time of concentration of 45 minutes. The Mankato land use can be approximated is 50% asphaltic surfaces and 50% grass areas in good condition with flat slope (average slope 1.5%). What size storm pipe is needed at the outlet of this watershed for 10-year design storm? Assume the storm sewer will be laid at a 1% slope and has a Manning roughness of 0.015. Use the customary method for design of storm sewers in small, developed areas. Show your work and circle the correct answer. 24-in 30-in 36-in 42-in 48-in
