SECTION 4

FLOW CALCULATION METHOD

This section enables the user to choose 

from two different flow calculation meth

-

ods:

a.Exponential Flow Method   

b.Flow Table entry Method

a.Exponential Flow Method 

usage:for flumes and weirs

To use this method,the user needs to 

know:

*The weir / flume exponent

*The maximum flow

There is provision for entering the Low 

Flow cutoff

Figure,although this is not manadatory.
