A field channel has cultivable commanded area of 2000 hectares. The intensities of irrigation for gram and wheat are $30 \%$ and $50 \%$ respectively. Gram has a kor period of 18 days, kor depth of 12 $\mathrm{cm}$, while wheat has a kor period of 18 days and a kor depth of $15 \mathrm{~cm}$. The discharge (in $\mathrm{m}^{3} / \mathrm{s}$ ) required in the field channel to supply water to the commanded area during the kor period is
