8.2.1 Water is not stratified

8.2.1.1 Multiport diffuser.- We have three different cases:

Case I: 

θ >=65º   F<=0.1 ó

θ <65º   F<=0.36

θ=angle between Ua vector and diffuser.

F=Fraude number F=Ua3 (g’q)-1

q=Unitary flor rate in the diffuser q=QLt-1 (m2/s)

Q=Discharge flow rate (m3/s)

Lt=Diffuser length (m)

S=initial dilution

In such a case, we have the next relationships

S=0.27 Ua H q-1 F-1/3

e=0.29H

B=SQ/eUa

Case II: 

25o=<θ <65º  F>0,36 (*)

In such a case, we have the next relationships

S=0.38 Ua H q-1

B=max[Ltsin θ; 0.93Lt F-1/3]

e=SQ/BUa
