WebWhen the pressure is expressed in terms of the equivalent height of a column of that fluid, as is common with water, the friction loss is expressed as S, the "head loss" per length of pipe, a dimensionless quantity also known as the hydraulic slope. where ρ = density of the fluid, (SI kg / m 3) g = the local acceleration due to gravity; WebThe equation can be represented as: where Q = flow (cubic metres per second) = coefficient of discharge A = area of orifice (square metres) g = acceleration from gravity (9.81 m/s^2) h = head acting on the centreline (m)? For a circular orifice, the equation becomes: Typical values for the coefficient of discharge are: Sharp orifice: 0.62

WebIn the chapter on head loss, it was determined that both frictional losses and minor losses in piping systems were proportional to the square of the flow velocity. Since flow velocity is directly proportional to the volumetric flow rate, the system head loss must be directly proportional to the square of the volumetric flow rate. WebFor ‘small diameter pipes’ friction losses in the pipe play a significant role and the head loss coefficient is estimated to equal: Symbols used: Q = Discharge (m 3 /s) D p = Siphon internal diameter (m) g = Acceleration due to gravity (9.81 m/s 2) Δh = operating head (m) Note: That head height will change when siphoning from a fixed volume.
