Supplemental Problem $3$: Flow Rate Units Mania

Group No$.q,$ Name $q,$

Background

Almost every hydraulics problem involves a knowledge of flow rate. Either we need to input flow rate or we are solving for it$.$ Interestingly, a variety of units are utilized even beyond the usual differences between English and metric. This exercise will introduce the conventional units for flow rate along with other units that are not conventional at all, but still fun to know. The goal is to sharpen your ability with unit conversion, an essential skill for technical professionals.

Question

Assume the flow rate in a piping system is $7f\frac{t^3}{sec}($cfs$).$ Convert this to the units listed below. You must show every step to receive credit. For example, converting $7f\frac{t^3}{sec}$ to $ga\frac{l}{m}in$ :

$7f\frac{t^3}{sec\frac{60sec}{1(min)}\frac{7\mathrm{.}48\text{g}\text{a}\text{l}}{1f{t}^3}}=?gpm$

$ga\frac{l}{m}in(gpm)$

$\frac{m^3}{sec(cms)}$

liters$/$min $($Lpm$)$

million gallons per day $($MGD$)$

furlongs $\frac{{?}^3}{?}$ fortnight $($Shakespearean$)$

light years $\frac{{?}^3}{?}$ millennium $($Star Trek$)$
