5. A weir is a slot in an open channel with water flowing over it (Figure 14.12). For a weir with a rectangular shape, the following formula can be derived:
Q = 5.35 Lh3/2
Where
Q = water flow rate. ft3/s
L = length of weir, ft
h = height of liquid above weir gate, ft
Do the following:
a. Determine the units associated with the constant that are needed to make the equation dimensionally homogeneous.
b. Determine a new constant that allows the following units to be used:
Q = water flow rate, gal/min
L = length of weir, ft
h = height of liquid above weir gate, in
