Simple Head Loss Calculation Example

Calculation of water head loss in the pipeline is very simple. In the head loss calculation example, we will consider in detail the calculation options. For hydraulic calculation of the pipeline, you can use the hydraulic calculator of the pipeline. From school physics lessons it is clear that the water flowing through the pipes, in any case, experiences resistance. The magnitude of this resistance depends on the flow velocity, the diameter of the pipe and the smoothness of its internal surface. The lower the resistance, the lower the flow speed and the greater the diameter and smoothness of the pipe. All these are taken into account while making head loss calculations.

The head loss calculation example presented here can help with assignment writing. The sample was made by an expert in engineering. Each writer’s experience in the field helps to deal with such tasks easily. However, you can find samples for other disciplines on our blog, for example, to get accounting homework help free online. Well, let’s start the calculation! Continue reading

Extended Euclidean Algorithm Example

The Euclidean algorithm is an effective algorithm for finding the greatest common divisor of two integers. It is named after the Greek mathematician Euclid, who invented in VII century.

In the most simple case, Euclidean algorithm is applied to a pair of positive integers and generates a new pair consisting of a smaller number, and the modulo between the larger and the smaller number. The process is repeated until the found number will be the greatest common divisor of the original pair.

The extended Euclidean algorithm also finds such coefficients x and y that:

a*x + b*y=gcd(a, b) Continue reading

Dijkstra’s Shortest Path Algorithm Example

Dijkstra’s shortest path algorithm finds the shortest paths between all nodes of the graph. In this article we will describe the operation principle of Dijkstra’s algorithm, which finds optimal routes. The disadvantage of this algorithm is that it will not work correctly if the graph has negative edge weights. In this tutorial you can read Dijkstra’s shortest path algorithm example. The author has solved a particular task and provided a vivid description of the solution. Following each step you will be able to solve a similar solution by yourself with ease.
