The peak of a flood hydrograph due to a 3-h duration isolated storm in a catchment is 180 m3/s. The total depth of 3-h rainfall is 2.7 cm and an average loss due to infiltration is 0.3 cm/hr. The peak discharge of the 3-hour unit hydrograph for a base flow of 30 m3/s is (in m3/s up to 2 decimal places)
