1.1.4. Examples in Pipe Systems

Now we coming back to the very simple examples okay. And that is what is in your text book is necessary to for. If you look it that, many of the times you have the pipes in series, pipes in parallel or three reservoir junction problems okay.

In this part, we introduce the basic setups encountered in pipe systems. We differentiate between series and parallel configurations and also mention the relevance of three-reservoir junction problems. Series pipes are similar to how current flows through a single path in electrical circuits, while parallel pipes have multiple paths through which fluid can flow.

Think of a water slide at a water park. If you have one slide after another (series), all water goes through each slide one after another. But if you have multiple slides that can be taken at the same time (parallel), the water can choose any slide to descend.

Pipe in series is a very simple problems like electric circuits, okay. You can have a series of wires you have from point A to B, okay. ... But if you are having a energy losses between delta h 1 is energy losses for this regions.

In a series configuration of pipes, the flow rate is constant through all pipes, meaning that the discharge (Q) remains the same. However, energy losses due to friction and changes in elevation must be summed over each pipe. Therefore, the total head loss is the sum of head losses from individual pipes. This creates a straightforward calculation model based on the fixed flow.

Imagine water flowing through multiple connected hoses. If one hose is kinked, it reduces the pressure throughout the entire system. To understand the energy loss, think about how much pressure is needed to push water through each kinked hose separately.

But when you have a pipe in a series please remember it that you always should consider whether there is a minor losses. ... the head energy losses along the pipe from pipe 1, pipe 2, pipe 3.

When analyzing a series pipe system, both major losses (friction from the pipe surface) and minor losses (losses due to fittings, expansions, and contractions) must be accounted for. This ensures accurate predictions of total energy losses and helps in designing efficient pipe systems.

Consider a long garden hose connected to various attachments. Not only does the friction inside the hose slow down the water (major loss), but also every attachment, such as a sprinkler or nozzle, creates additional obstacles, causing more water pressure to be lost (minor losses).

Now if you look it another very simple problems that pipes in parallel. ... So sum of the discharge will give us the discharge what is passing through the A or B and the energy losses whether following the 1 path 2 path or 3 path should be equal.

In a parallel pipe configuration, multiple paths allow water to flow simultaneously, similar to how traffic can divide into multiple lanes on a road. Here, the energy loss in each path must be equal, meaning that if one path has higher resistance, the fluid will adjust its flow accordingly. The total flow entering the parallel system equals the sum of discharges in each of the outlets.

Think about highways in a city where traffic can take multiple routes. Even if one route is jammed, cars will divert to other routes, making sure the total number of cars trying to reach the city center remains constant, just like how fluid divides and takes different paths based on resistance in parallel pipes.

Now if you look it the three reservoir junction problems which many of the time it is given that you have a multiple reservoirs ... That is what we apply with a loss and compute what is the head losses should be there in this direction.

At a junction with three reservoirs, the principle of mass conservation applies, meaning the total incoming flow minus the outgoing flow must equal zero. The head (energy) loss must also be calculated across the junction to understand how much fluid can exit through various pipes. By understanding this, engineers can ensure that the system is designed to maintain sufficient pressure and flow.

Think of a water park where three different slides (reservoirs) are connected at a point. If too many kids (fluid) go down one slide while the others remain unused, it might drain some slides faster than others, leading to flow imbalances. We must ensure that water can continuously flow by analyzing how much is lost at each junction.

Let us start this third examples which is gives that 2 kilometer long pipe with a diameter of 0.2 meter ... additional things what will consider it, but other losses we will not consider this case as given in the problems.

This example illustrates a typical examination scenario where students must calculate the average velocity of the fluid flowing through a long pipe with defined friction losses. By understanding both major and minor losses, students can apply the concepts learned to find the effective flowing speed, indicating how friction and energy loss impacts the flow.

Imagine a long water slide where the speed of water changes due to friction against the slide's surface. The height difference between two ends of the slide represents potential energy that can be lost through friction, similar to how we lose energy in pipes; calculating these losses helps to find out the water's speed at the bottom of the slide.
