Pipes function as a distribution medium from one place to another. In the process of distributing fluids using pipes, there are several problems that will occur, namely pressure drop. The cause of the decrease in pressure in a fluid is caused by several things such as the diameter of the fluid, the friction force of the fluid, and the physical properties of the fluid. Pressure drop occurs due t…
In a means of transportation or fluid installation, there will definitely be the use of fittings, where these fittings will cause an obstacle to a flow. Resistance to the flow will cause a decrease in the energy of the fluid, this phenomenon is often also called energy loss (head loss). This is important to identify because it has an important role, namely to find out the amount of loss value t…
