Question $3[10$ points$]$:

The irrigation ditch $($surface roughness $=0\mathrm{.}017$ in$.)$ shown in the figure below has a cross section $2m$ wide $2m$ deep. It conveys water from location $1$ to location $2,$ between which there is a $1m$ drop in elevation. With a flow rate of $Q=2\frac{m^3}{s}$ of water, the ditch is filled to a depth of $1\mathrm{.}2m.$

i$.$ Is the flow laminar or turbulent?

ii$.$ Find the friction loss from locatoin$1$ to location $2.$

iii. What is the distance between location $1$ to location $2?$
