I think answer is 1. Since excess rainfall in unit hydrograph always in 1 order ie 1mm or 1 cm.

Vasanth S D said: (Jul 11, 2018)  
It is 1 cm only not mm.

10/2.5 = 4.

Duhan said: (May 12, 2019)  
Best unit duration of storm for a UH is assuming 1/4 of basin lag so it's divided by 4.

UH is assuming 1/4 of basin lag so it's divided by 4.

Nabinkafle said: (Feb 16, 2020)  
The synthetic unit hydrograph developed above is for a particular duration (Tr) of the storm, if the unit hydrograph of another duration D is required then the basin lag (Tl) is modified as Eqn= (Tl + (D-Tr/4) ).

So the answer is 4 definitely no doubt.
