Abstract

Fluids often experience a loss of energy (head loss) in the pipe due to flow turbulence, which results in friction on the inner surface of the pipe. Head loss is very detrimental in piping systems because it can reduce the level of fluid flow efficiency. Head loss is affected by variations in bends (elbows), joints, valves, and pipe diameters. The purpose of this study is to determine the head loss that occurs in each line of the fluid flow piping system, which consists of variations in the cross-sectional area of the pipe and the number of connections, valves, and bends. In addition, it is also used to evaluate pump work in series and complex circuits. The smaller the diameter, the more the fluid velocity increases, causing the friction in the pipe to increase and the head loss to increase. The pump work required to flow the fluid is directly proportional to the amount of head loss that occurs in the piping system.

Abstract

The industrial production process is closely related to control systems, including level control. This is often used to ensure that fluid in the tank is available in the appropriate amount at each stage of the process. The process typically uses an automatic control system such as a Proportional Integral Derivative (PID) Controller that can help measure the accuracy of the data obtained. Therefore, this study aims to examine the effect of flow rate on fluid level control in a tank using linear, exponential, and logarithmic regression analyses. In the process, the effect of the automatic control system (PID Controller) on fluid flow rate was evaluated. The materials used were a 4 mm solenoid and a pump speed variation in the range of 30-50%. Data on fluid level increase were obtained at 0 (n = 1), 60.27 (n = 30), and 180 seconds (n = 61) as the lower, middle, and upper limits. The results showed that fluid flow rate significantly affected the process of controlling fluid level in the tank, and is influenced by the speed of the pump used. Based on the regression analysis, the evaluation of the PID Controller was still classified as good, because the deviation observed in the reading flow rate data was very small.
