Number of riser pipes

minor loss coefficient for rapid mix

Combined area of all orifices

function for determining the orifice areas as the vertical distance on the riser pipe increases

headloss through the Lfom, and the minimum height of the water in the entrance tank

minor loss coefficient for an orifice (was K orifice)

plant flow rate

the inner diameter of the riser pipe

ratio of LFOM pipe area to orifice area

nominal diameter of the riser pipe and rapid mix pipe

enumerated type of pipe

rapid mix head loss

The total pipe length betweeen the bottom of the orifices and the flocculator

viscosity of water through the plant

PVC pipe roughness

Function based off of ramp functions, this is an incremental function that all ows other funtions to evaluate one level of orifices at a time

vertical distance between orifices

elevation between orifice rows at which the flow is calibrated, a 0 or 1 value. 0 corresponds to the current row and 1 corresponds to the next row

funtion to determine target riser pipe flow, incrementally calculates flows

funtion to determine actual flow through orifices

number of orifices

diameter of Lfom orifices

function that determines the diamter of a circle given the area

function that determines the drill bit size necessary

arbitrary value determines the number of orifices in the first row, currently 5 is selected

percent error in the actual flow rate compared to theoretical values

maximum error of Q_LfomError array

headloss from the entrance tank to the flocculator

water depth of entrance tank relative to the bottom of the sedimation tank

height of the start of the floculation tank relative to the bottom of the sedimention tank

difference between height of water in floculation tank and the bottom set of orifices on the LFOM

maximum water level in entrance tank

minimum water level in entrance tank

height of entrance tank walls

height of entrance tank above the top of the riser pipe

safety factor of height of riser pipe above top row of orifices

height of the riser pipe
