Web1- Determine the Flow Rate of Water: The first step in designing the right capacity of UV system for a commercial RO plant is to determine the flow rate of water. The flow rate is the amount of water that passes through the UV system in a given time. The flow rate of water depends on the size of the commercial RO plant, the daily water ... WebAfter the system head has been calculated, it can be used to calculate an approximate pump power rating for a centrif- ugal pump: where Pis the pump power (kW), Qis the flowrate …
WebThis article provides calculation methods for correlating design, flow rate and pressure loss as a fluid passes through a nozzle or orifice. Nozzles and orifices are often used to deliberately reduce pressure, restrict flow or to … Webto deliver a specified flow rate (gallons per minute) within certain pressure limits. • Each code lists procedures for calculating design flow rates that are directly related to the number of plumbing fixtures within the building. (Check UPC-1997, Appendix A; SPC-1997, Appendix F; IPC-1995, Appendix E; CABO- 1995, Sect 3409).
WebFormula for calculating consumption: Total heat loss at home (kW) x 0.044 = flow rate of the circulation pump (m3 / hour) For example, if the area of a private house is 800 sq. M. the required flow rate will be equal to: (800 x 100) / 1000 = 80 kW - heat loss at home. WebBOD, lb/day = BOD, mg/L x Flow, MGD x 8.34 lb/gal BOD, lb/day = 180 mg/L x 2.25 MGD x 8.34 lb/gal BOD, lb/day = 3,377.7 lb/day Example: The BOD concentration of the wastewater entering an aerator is 220 mg/L. If the flow to the aerator is 850,000 gpd, what is the BOD loading in lb/day? BOD, lb/day = BOD, mg/L x Flow, MGD x 8.34 lb/gal
