We do not release any material for production until a satisfactory material certificate is received.

5 Pipe Fittings, Joints and Valves

per the requirement. Fittings are fixed in the plumbing system to join straight pipes or any section of tubes. We can say that the water-supply fittings like elbow, tee, socket, reducer, etc., are fitted to change the direction of flow, distribute the water supply from the main pipe to other pipes of equal size or lower size, etc.

Pipe Fittings Loss Calculations with K Factors

Manufacturers of pipe work fittings and valves often publish a fitting's associated 'K' factor. Pipe Fitting Loss Formula. Fluid head loss through a fitting can be calculated by the following equation: h = K x v² / 2g where h = pressure loss in terms of fluid head, i.e. fluid head loss K = manufacturer's published 'K' factor for the fitting

Pressure Loss from Fittings - Equivalent Length Method ...

Fittings such as elbows, tees and valves represent a significant component of the pressure loss in most pipe systems. This article details the calculation of pressure losses through pipe fittings and some minor equipment using the equivalent length method. The strength of the equivalent length method is that it is very simple to calculate.

Valve Characteristics - Quick Opening, Linear & Equal ...

The below mentioned flow equation describe the flow rate of a fluid through a valve. The form of this equation used by valve suppliers is: where C is the valve flow coefficient, q the flow rate of the liquid through the valve, Δp = p1 – p2 the pressure difference across the valve and G the specific gravity (relative density) of the fluid.

Fittings and Valves Equivalent Length - spikevm

Calculate friction losses for fittings and valves in a section of pipe expressed in equivalent length of pipe (in feet). Example: Your section of 2" pipe has 2 x gate valves, 2 x 90° elbows, 4 x straight true tee's and 12 branch tee's Select 2" for nominal pipe size and enter 2 gate valves, 2 90° elbows, 4 straight true tee's and 12 branch tee's.

the supply source. These pressures are as follows: 1. Pressure required at fixture to produce required flow. See 607.3 and 607.4. 2. Static pressure loss or gain (due to head) is computed at 0.433 psi per foot (9.8 kPa/m) of elevation change. Example: Assume that the highest fixture supply outlet is 20 ft (6.1 m) above or below the supply source.
