Using the Modified Puls Method, calculate the outflow hydrograph if $t=10$min, the inflow hydrograph is given by below and the weir equation is

$Q=(\frac{2}{3})C_e\sqrt[\phantom{2}]{2g}L(h-h_0{)}^{1\mathrm{.}5}$

Assume $C_e=0\mathrm{.}7,h_0=4\mathrm{.}5ft,g$ is the gravitational acceleration and $L=15ft.$

$\backslash$table$[[h(ft),$Volume $(f{t}^3)$

Give me the detailed steps of calculations in excel sheet
