Expansion Loops in 2D & 3D
Expansion Loops in 2D & 3D: Enhancing Piping System Flexibility In instances where thermal displacements within a piping system exceed a specific threshold, the incorporation of expansion loops becomes imperative to absorb these displacements. According to ASME B31.3, part 319.7, piping expansion loops stand out as one of the most effective methods for increasing the […]
Bernoulli’s Theorem
Bernoulli’s theorem, named after the Swiss mathematician and physicist Daniel Bernoulli, is a fundamental principle in fluid dynamics. It relates the pressure, velocity, and gravitational potential energy of a fluid along a streamline. The theorem is derived from the principle of conservation of energy applied to a flowing fluid. Bernoulli’s theorem is valid for incompressible […]
Thermodynamics – Surface for water
Thermodynamics studies the relationship between heat, work, and energy in a system. Phase diagrams and various graphical representations, such as p-v (pressure-volume) and T-v (temperature-volume) diagrams, are essential tools in thermodynamics to understand and analyze the behavior of substances under different conditions. 1. Phase Diagrams: A phase diagram is a graphical representation that shows the […]
Venturi Flowmeter
A Venturi flowmeter is a type of flow measurement device that operates based on the principle of Bernoulli’s equation. It is designed to measure the flow rate of a fluid (liquid or gas) through a pipe by creating a constriction in the flow path. Here’s a brief description of how a Venturi flowmeter works: Constriction: […]
Nominal Effective Length
Will it buckle? When subject to compression loads, slender beams might buckle, leading to potential catastrophic failures in critical structures. One way to determine the critical buckling load for an idealized member is by utilizing Euler’s elastic buckling formula. Pcr = (E*I*π^2) / ((K*L)^2) The formula shows the relationship between E – elasticity modulus, I […]
Understanding and Preventing Slug Flow in Process Piping Systems
Introduction: Slug flow is a multiphase flow phenomenon observed in piping systems, characterized by the periodic formation of liquid slugs projected at a high (gas) velocity. This phenomenon can lead to dynamic fluid forces due to changes in momentum, inducing vibrations that may result in structural damage. To mitigate the risks associated with slug flow, […]
