The flow rates measured during a precipitation at the outlet of a basin with an area of 10800 hectares are given below. It is assumed that the precipitation intensity is constant 50 mm/hr and the infiltration index of the basin is 10 mm/hr. Determine the duration of the unit hydrograph and obtain the 60-minute unit hydrograph of the basin. You can take the base flow as 100 m³/s.
