K – loss factor – has no units (dimensionless) Sudden enlargement. Energy lost is because of turbulence. Amount of turbulence depends on the differences in pipe diameters . 2 ( /2 ) L = 1 h K v g. The values of K have been experimentally determined and provided in Figure 10.2 and Table 10.1. 3, 49 rows · Summary. Fittings such as elbows, tees, valves and reducers represent a significant.
We can refer below equations in order to determine the friction factor . Minor Head loss . As we have discussed above minor head losses are pressure losses in pipe flow system due to various piping components such as valves, fittings, elbows, contractions, enlargement, tees, bends and exits. Where K is termed as minor loss coefficient and values …

Minor or Dynamic Loss Coefficients for Pipe or Tube System …
Pipe fittings, valves and bends usually have some associated K factor or local loss coefficient, which allows the calculation of the pressure loss through the fitting for a particular fluid flowing at a specified velocity. Manufacturers of pipe work fittings and valves often publish a fitting’s associated ‘K’ factor. Pipe Fitting Loss Formula, Minor loss coefficients for commonly used pipe and tube system components: Example – Minor Dynamic Pressure Loss in Waterflow a Ball Valve 1/3 Closed The minor loss a ball valve with flow velocity 2 m/s with water with density 1000 kg/m 3 can be calculated as ?pminor_loss = (5.5) (1000 kg/m3) (2 m/s)2 / 2, “Major” losses occur due to friction within a pipe, and “ minor” losses occur at a change of section, valve, bend or other interruption. In this practical you will investigate the impact of major and minor losses on water flow in pipes. Major losses Minor losses where. f = friction factor . k = minor loss coefficient. L = Length (m) D …
