This document discusses formulas related to fluid flow in pipes. It lists the names of group members and describes the major losses due to friction and minor losses due to entrance/exit, changes in cross-section, valves, bends, and elbows. It then summarizes Darcy's formula for head loss due to friction and provides the variables in Chezy's formula for velocity of flow in an open channel.
Minor losses are a major part in calculating the flow, pressure, or energy reduction in piping systems. Liquid moving through pipes carries momentum and energy due to the forces acting upon it such as pressure and gravity. Just as certain aspects of the system can increase the fluids energy, there are components of the system that act against the fluid and reduce its energy, velocity, or momentum. Friction and minor losses in pipes are major contributing factors.

The forth lecture in the module Particle Technology, delivered to second year students who have already studied basic fluid mechanics.
Fluid flow in porous media covers the basic streamline and turbulent flow models for pressure drop as a function of flow rate within the media. The Modified Reynolds number determines the degree of turbulence in the fluid. The industrial processes of deep bed (sand) filtration and fluidisation are included.
OPEN CHANNEL FLOW AND HYDRAULIC MACHINERY
Open channel flow: Types of flows – Type of channels – Velocity distribution – Energy and momentum correction factors – Chezy’s, Manning’s; and Bazin formula for uniform flow – Most Economical sections. Critical flow: Specific energy-critical depth – computation of critical depth – critical sub-critical – super critical flows
Non-uniform flows –Dynamic equation for G.V.F., Mild, Critical, Steep, horizontal and adverse slopes-surface profiles-direct step method- Rapidly varied flow, hydraulic jump, energy dissipation
Fluid Mechanics
Internal and External Flows
Part A
Friction factor, Pipe losses, Boundary Layer, Over external bodies, Flow Separation and control methods, Lift generation, Flow simulation methodology
Part B

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

experiences some resistance to its motion,
whose effect is the velocity and ultimately
the head of water available. An empirical
formula for the loss of head due to friction
was derived by Henry Darcy

11. Chézy was born at Chalon-
sur-Marne, France, on
September 1, 1718, and
died on October 4, 1798.
He retired in 1790 under
conditions of extreme
poverty. It was not until
1797, a year before his
death, that the efforts of
one of his former
students, Baron Riche de
Prony, finally resulted in
Chézy's belated
appointment as director of
the Ecole des Ponts et
Chaussées.
