$Pb1.$ Direct runoff from flood over a basin of $50$ hectare was observed as $25000m^3$ during a storm. Equivalent depth of rainfall over the basin was $97mm.$ Determine the w$-$index. $-$index if time distribution of rainfall is as:

$\backslash$table$[[$Time $($hr$)0,1,2,3,4,5,6],[$Rainfall $($mm$)0\mathrm{.}0,6\mathrm{.}0,11\mathrm{.}0,34\mathrm{.}0,28\mathrm{.}0,12\mathrm{.}0,6\mathrm{.}0]]$
