This program will code for a general dose controller design and will incorporate the design into the Automated Design Tool. The doser design will be for a triple scale (three different orifices). See the CDC research team for a more detailed explanation for this design (https://confluence.cornell.edu/display/AGUACLARA/Effect+of+surface+tension).

h3. Design Process:
Expert Inputs:
HL.ChemDoserMin
User Inputs:
Q.Plant (HL.Plant)
Design Assumptions:
C.DoserScaleAlumMax
Code Calculations:
Constant head tank orifice size
Dosing tubes size to ensure orifice head loss is much greater than major loss in tubing
h3. Equations:
Orifice Equation:
{latex}\large $$ Q = K_{vc} A_{or} \sqrt {2gh} $$ {latex}
Where, \\
{latex}\large$$ Q = Flow Rate $${latex}
{latex}\large$$ h = Head Loss $${latex}
{latex}\large$$A_{or}= Area of the Orifice $${latex}
{latex}\large$$K_{vc}= Orifice Constant $${latex}
Orifice Head Loss:
{latex}$$
h_{1Orifice} = K_{DoseOrifice} {{V_{DoseTube}^2 } \over {2g}}
$${latex}
Major Head Loss:
{latex}$$
h_{Lmajor} = f {L\over {D}}{{V^2} \over {2g}}
$${latex}
