Linear Orifice Flow Meter Variable Description Table: in order of appearance in code
Variable Name | Variable Description | ||
|---|---|---|---|
| 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 |
