Design flow rate formula

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. 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 …
