### Sample Problem - Equivalent Length Calculation for …

Along with the original 200 m of straight pipe, the total equivalent length of the given 6" line becomes 260.36 m. This length can be used to quickly calculate variation of pressure drop for minor variations in the flowrate, using EnggCyclopedia''s pipe pressure drop.

### Flow in pipe

Physical values in Darcy formula are very obvious and can be easily obtained when pipe properties are known like D - pipe internal diameter, L - pipe length and when flow rate is known, velocity can be easily calculated using continuity equation.

### Pipe Elbows - Long/Short Radius, 45°|90°|180° Elbows

An elbow is a pipe fitting which is used as a connection point between two lengths of pipes to produce a change in the direction of flow in the pipe, usually at an angle of 90 , 45 or 180 . Elbows are also commonly referred as bends, and are available in a range of materials such as stainless steel, carbon steel, alloy steel, nickel alloys, duplex, and cupro nickel.
