Pressure Loss from Fittings – 2K Method – Neutrium

Oct 17, 2012· Introduction. The 2K method allows the user to characterise the pressure loss through fittings in a pipe. As the name suggests, two K coefficients are used to characterise the fitting, which when coined with the flow conditions and pipe diameter may be used to calculate the K-value (excess head), which is in turn used to calculate the head or pressure loss through the fitting via the excess

Some Friction Loss Tables

Example: Determine L (friction loss in pipe fittings in terms of equivalent length in feet of straight pipe). Assume a 6" angle valve for Schedule 40 pipe size. Select the appropriate K value for such and select D and f for Schedule 40 pipe from the table below where K is the pipe diameter in feet.

Modeling a Tee - Engineered Software Knowledge Base

Modeling a Tee. by Engineered Software, Inc. Users often inquire about the correct way to account for the losses through a Tee fitting. PIPE-FLO Professional utilizes the fitting methods described in the Crane Technical Paper 410: Flow of Fluids Through Valves Fittings and Pipes. The TP-410 provides just two L/D values for Tees that are use to calculate the K resistance values; 20 for Flow

NFPA Valves and Fittings Tables - Engineered Software

Then, depending on the C value and the pipe inside diameter in relation to steel schedule 40 inside diameter, there are factors to multiply the equivalent length by. Tables 1-4 show the equivalent lengths as specified by the NFPA 15 Standard for a variety of valves and fittings for Schedule 40 steel pipe with a C value …

Within the Pipe Flow Wizard software the type and quantity of bends, valves and other fittings associated with the pipe can be set by amending the quantity values on the ''Pipe fittings'' screen.

2-k Method For Excess Head Loss In Pipe Fittings

2-k Method For Excess Head Loss In Pipe Fittings - posted in Industrial Professionals: Dear All,Crane paper 410M gives method for finding equivalent length of pipe fittings for fully turbulent flow based on friction factors for fully turbulent flow as given in Appendix A-26. The Crane method however does not give an idea about how to calculate excess head loss or resistance coefficient K when

9. FRICTION LOSS ALONG A PIPE - FIT Staffweb

9. FRICTION LOSS ALONG A PIPE Introduction Where there are numerous fittings and the pipe is short, the major part of the head loss will be due to the local mixing near the fittings. For a long pipeline, on the other hand, skin friction at the pipe wall the wall to a maximum value U at the centre of the pipe. The mean velocity V is of

Black Fittings , Black Pipe Fittings , Ward Black Fittings

Black iron pipe is also a popular choice in fire sprinkler systems due to its high heat resistance and for water supply lines due to its resistance to water damage. These fittings derive their name from the black oxide scale covering their surface. There are many different types of black fittings, each serving a particular function.

Minor Losses in Pipes

liquid flows into the pipe from the larger area. As shown in Figure-4, the k-values for entrance losses range from 0.04-0.8. Upon exiting a pipe the velocity is assumed to go down to zero which makes the loss equal to the velocity head. This total loss makes the k-value equal to 1 in all cases and is also displayed in Figure-4.

K Value and Pipe Length Calculator

This calculator shows the relationship between the K value and pipe length. The K value for various fittings has been arrived at through experimentation. For any valve, a length over diameter (L/D) coefficient can be determined by equating the pressure drop through the valve to the equivalent length of pipe measured in pipe diameters.

Resistance coefficients (K values) for pipe fittings like

The second page covers elbows and tees. The resistance coefficients (K values) for the elbows and tees are calculated using the Darby 3-K Method which allows accurate calculation of pressure drops in the fittings for laminar and turbulent flow. This gives better accuracy than using equivalent lengths or fixed K values.
