The direct runoff ordinates of a complex storm made up of 3 effective rainfall bursts are given below:

Time (in hour)	0	2	4	6	8	10	12	14	16	18	20	22	24
Ordinate(cumec)	0	6	16	22	38	23	31	54	32	18	9	3	0

This hydrograph is generated by three 4 hour effective rainfalls having 1 cm, 2 cm and 3 cm effective rainfalls respectively. Second rain burst follows the first. However the third burst starts after a break of two hours from the end of the second burst. Using complex hydrograph analysis method what is the peak value (in cumec) of the 4 hour unit hydrograph.
