WebThis reduction in pressure due to friction between the flowing fluid and solid wall is commonly known as head loss. The engineering designs of such piping networks are mainly done using the head loss coefficient ( K) also known as K -factor. The head loss coefficient ( K) in various pipe fittings is predicted using Equation (2) . WebThe 3 methods which are used to calculate the minor losses in pipe sizing exercises are the equivalent length (L e /D), the resistance coefficient (K) and the valve flow coefficient (C v ), although the C v method is almost exclusively used for valves. When the pressure drop across a fitting is expressed in terms of Resistance … Try AioFlo for free before you buy. Testing AioFlo is risk free. Download and test …
WebPressure drop or head loss is proportional to the velocity in valves or fittings. For the most engineering practices it can be assumed that pressure drop or head loss due to flow of fluids in turbulent range through valves and fittings is proportional to square of velocity. WebThe permanent pressure loss through the orifices is calculated using the Hooper Method. Generic resistance coefficient (K value) data is included for gate valves, globe valves, …
