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 ... Webcurrent average daily flow based on the last three years data. This is done by averaging the daily flow for each year, then averaging the three years. For a proposed facility, it’s the project initial flow. To evaluate and address low flow conditions (minimum flows) Design Average Flow (Design Capacity) Average daily flow a facility is
WebFlow rate (gpm) = Velocity (ft/s) x Area (in2) 0.3208 Note: Fluid is pushed or drawn into a pump Pumps do not pump pressure, their purpose is to create flow. (Pressure is a result of resistance to flow). Torque and horsepower relations: T = HP x 63025 ÷ RPM HP = T x RPM ÷ 63025 RPM = HP x 63025 ÷ T T = Torque, inch-lbs RPM = Speed, revs / minute WebThe design of sewers is done in such a way that the velocity of flow in the sewer attains the self-cleansing velocity at the minimum hourly rate of flow. The minimum hourly rate of flow is the flow rate that occurs during the dry weather period. The sewer is designed to achieve a velocity of flow that is 25% higher than the self-cleansing velocity.
