Example 1 ‘V’ Notch Weir
The application is to be assigned to Point (transducer) 1.
In this example it is required to calculate the flow through a Simple
Exponential Device, which on this occasion is a V-Notch Weir. The K factor
for the weir is unknown so ratiometric calculation will be used, and the flow
rate is to be calculated in millions of US gallons/day.
The distance from the end of the transducer horn (dB Mach 3) to zero flow
(P105) is 40 inches and max head (P704) is 15 inches, maximum flow
(P705) is known to be 2.2million US gallons/day.
