The friction factor for fluid flow can be determined using a Moody chart. The friction factor for laminar flow is independent of roughness of the **pipe's** inner surface. f = 64/Re. Head **loss in pipe** flow system due to viscous effect i.e. due to friction will be termed as **major** head **loss** and will be indicated by h L-**Major**. Head **loss in pipe** flow system due to various **piping** components such as valves, fittings, elbows, contractions, enlargement, tees, bends and exits will be termed as **minor**. friction factor, or **major losses**. These **losses** can be grouped into **major** **and** **minor** **losses**. The **major** **losses** come from the friction and length of the **pipe**, while the **minor** **losses** come from the way that the **pipe** bends, turns, expands, and contracts. The experiments showed what the effect of these **losses** were **and** which fittings mitigated these effects. The energy **losses** that occur during steady state conditions are classified into two categories, the **major** **losses** **and** the **minor** **losses**. **Major** **losses** occur due to the friction effect **between** the moving fluid and the walls of the **pipe**. The **minor** **losses** occur due to any disturbance that might occur to the flow, which is mainly caused by the. **losses**. **In** other words, the **losses** that occur in pipelines due to bends, elbows, joints, valves, etc. are sometimes called **minor** **losses** .**In** case of a very long **pipe**, these **losses** are usually.

Give at least three examples of **minor** **losses**? (5 points). **Minor Losses** in **Pipes** . The **minor loss** experiment was conducted in 25mm galvanised steel **pipe** , which means you have can determine velocity. You will need to refer to your calculations from the **Major Losses** part of the experiment in order to determine an appropriate value for λ. You can either calculate λ using the Moody equation (or diagram) from the k/D value you.
