Fitting pressure drop k or hooper
WebA less traditional approach is the two-k method developed by Hooper (1981), which correlates the pressure drop coefficient with the Reynolds number and the fitting diameter through the following equation: kkf1=+Rek∞(1+1D) (11) MATERIALS AND METHODS Model Fluids Solutions of xanthan gum (Star & Art, Brazil) and WebFriction Loss in Fittings Valves As an aid, liquid sizing constants (Cv values) are shown for valves. These values are defined as the flow rate through the valve required to produce a pressure drop of 1 psi. To determine the pres-sure drop for a given GPM the following formula may be used. ∆P = (G2)(SG)/Cv2 where: AP = pressure drop G= Flow ...

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) . WebPressure drop due to head loss in pipe is calculated as ΔP = hTotal.ρ.g where, ρ is fluid density. There are several methods for estimating pipe fitting losses like equivalent …
