 Althi.Santosh said: (Oct 27, 2015) Why answer is only 4?

 Sak said: (Mar 13, 2016) How its come ?

 Biswajit Swain said: (Mar 30, 2016) Why the answer is 4, explain?

 Vijay said: (Oct 5, 2016) How its came? Describe me.

 Asif said: (Jan 2, 2017) Explain it please.

 Gayatri said: (Jun 25, 2017) Explain it please.

 Ashley said: (Oct 22, 2017) Anyone explain this please.

 Kshitiz Gautam said: (Jan 15, 2018) 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.

 Vishal Gupta said: (Jan 25, 2019) 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.

 Jayank said: (Jul 26, 2019) 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.
