fundamentals of Piping engineering
This Presentation is about the basic fundamentals one needs to know to begin Piping Engineering. All the basic formulas and questions that are usually asked in interviews are answered in this presentation. Feel free to ask any doubts in the comments and iI may try my best to answer them for you.
Pressure Relief valve sizing and design
Safety is the most important factor in designing a process system. Some undesired conditions might happen leading to damage in a system. Control systems might be installed to prevent such conditions, but a second safety device is also needed. One kind of safety device which is commonly used in the processing industry is the relief valve. A relief valve is a type of valve to control or limit the pressure in a system by allowing the pressurised fluid to flow out from the system.
Pressure Relief Devices_Presenation
The document summarizes the basics of pressure relief devices, including why they are required, common components, classification and types. It provides examples of relief scenarios and causes of overpressure. The key steps in relief device sizing calculations are outlined. An example calculation is shown for checking the adequacy of installed relief devices for a reactor system during an emergency relief scenario involving an external fire.
Basics of two phase flow (gas-liquid) line sizing
This document discusses two-phase flow line sizing for liquid-gas flows in piping systems. It describes the different flow regimes that can occur using Baker's flow regime map. The key steps outlined are: 1) determining the flow regime based on fluid properties and flow rates, 2) calculating pressure drops for the liquid and gas phases separately using correlations, 3) using a multiplier to determine the two-phase pressure drop based on the flow regime, and 4) summing pressure drops from friction, elevation changes, and fittings to obtain the total pressure drop. Care must be taken to size each pipe segment separately as properties and regimes can change along the line.
Three Phase Separators
Three phase separators separate gas, oil, and water. They consist of three zones: an inlet zone, a liquid-liquid settling zone, and a gas-liquid separation zone. Key factors that affect separator efficiency include the inlet flow pattern and devices, feed pipe geometry, entrainment, and internals. Separators can be horizontal or vertical, with horizontal separators often used for foamy streams and liquid-liquid separation, while vertical separators handle large liquid slugs. Proper sizing considers flow rates, residence times, velocities, and droplet sizes to achieve efficient phase separation with minimum carryover.
Piping Design ppt.pdf
This document provides information on various piping drawings used in piping design and installation. It discusses process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), piping isometrics, plot plans, and general arrangement drawings. PFDs show the major equipment and process flows at a high level, while P&IDs provide more detailed piping information along with instrumentation and control schemes. Piping isometrics are used for fabrication and show piping runs at an angle for clarity. General arrangement drawings indicate equipment locations and piping layouts from a plan view. Together these drawings provide the necessary information for proper piping system design, installation, and operation.

METHODOLOGY FOR SLUG CATCHER SIZING
Oil & Gas Pipelines are often subjected to an operation called ‘Pigging’ for maintenance purposes (For e.g., cleaning the pipeline of accumulated liquids or waxes). A pig is launched from a pig launcher that scrapes out the remnant contents of the pipeline into a vessel known as a ‘Slug catcher’. The term slug catcher is used since pigging operations produces a Slug flow regime characterized by the alternating columns of liquids & gases.

The term slug catcher is used since pigging operations produces a Slug flow regime characterized by the alternating columns of liquids & gases. Slug catcher’s are popularly of two types – Horizontal Vessel Type & Finger Type Slug catcher. However irrespective of the type used, the determination of the slug catcher volume becomes the primary step before choosing the slug catcher type.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
