A suppressed rectangular weir is to be installed to measure flow rates in the range of $\backslash (0\mathrm{.}5-1\mathrm{.}0\backslash$mathrm$\{$m$3\}/\backslash$mathrm$\{$s$\}\backslash ).$ If the maximum $($total$)$ depth of water that can be accommodated upstream of the weir is $1$ m and the width of the channel is $4$ m $,$ determine the crest height of a suppressed weir that should be used to measure the flow rate $($to the nearest $0\mathrm{.}01$ m $).$
