An irrigation canal with a given cross-section is desired to be dimensioned hydraulically in the most appropriate way. The canal is made of concrete and has a slope of 1/m. The flow rate of the water passing through this canal is given in Q m^3/s, the Manning roughness coefficient n and the bottom slope of the canal in the data sheet. a) Find y and B values that give the most suitable cross section. b) If you want to pass this open canal with the help of circular pipes under a highway with the same inclination, how many D diameter pipes should be used? (pipe roughness: give in the table).
