Problem $1$: Use following data for a $60$ min storm, what is the total depth of rainfall for the storm? What is the maximum and minimum intensity and graph storm Hyetograph, with ordinates in $m\frac{m}{h}r.[5$ marks$]$

$\backslash$table$[[$Storm time$($min$),10,20,30,40,50,60],[\backslash$table$[[$Rasinfall depth$],[($mm$)]],0\mathrm{.}5,2\mathrm{.}5,5\mathrm{.}5,3\mathrm{.}5,1\mathrm{.}5,3]]$

Problem $2$: Use the same data as given above and graph storm Hyetograph for a $20$ mins, $30$ mins and $60$ mins time scale. $[7$ marks$]$

Problem $3$: Given below is rainfall hyetograph, answer the following questions. $[8$ marks$]$

a$.$ Compute total depth and average rainfall intensity for the storm.

b$.$ Compute the maximum depth and average rainfall intensity for the first $2\mathrm{.}0$ hours and last $1\mathrm{.}5$ hours of storm.

c$.$ Compute cumulative raimall for the storm and draw the mass curve diagram.
