PPT is a short and the most convenient way to understand a chapter. •Also it is assumed that reservoirs are very lagged and the water surface levels in the reservoirs are constant so that steady conditions exist in the pipes. ∂v / ∂s = 0 • The flow in which velocity at a given time changes with respect to space (length of direction of flow) is called as non- uniform flow. Calculate frictional losses for laminar and turbulent flow through circular and non-circular pipes. 2 4 Q DV π = where D is the pipe diameter, and V is the average velocity. During uniform flow, the terminal velocity reached, and the head loss equals the elevation drop We can the solve for velocity (or flow rate) Where C is the Chezy coefficient. 80 10, 0. ”. One PPT of Flow Through Pipes - Fluid Mechanics for Civil Engineering. E. Objectives Have a deeper understanding of laminar and turbulent flow in pipes and the analysis of fully developed flow Calculate the major and minor losses associated with pipe flow in piping networks and determine the pumping power Flow through Pipes in Series and Parallel: Difference Diameters, Equations and Solved Problems! Pipe in Series: Pipes are said to be in series if they are connected end to end (in continuation with each other) so that the fluid flows in a continuous line without any branching. • True when there are short, sudden geometric changes. If the water level in smaller dimension is 3m above that of larger. It is used for measuring the rate of flow of a liquid through a small channel of tank. PPT - FLOW IN PIPES PowerPoint Presentation, free 22. The document discusses key concepts related to pipe flow including laminar and turbulent flow, Reynolds number, velocity profiles, friction factors, head losses, minor losses, and pipe networks. 2 m with length 4m at the end of this pipe a Gate Valve is fixed as shown. Objectives • Have a deeper understanding of laminar and turbulent flow in pipes and the analysis of fully developed flow • Calculate the major and minor losses 4 Fig. g. Suppose a pipe line consists of a Flow of Fluids in Pipes Dr. Energy Fuels, 2012. 26: p. Flow Through Pipes in Series or Compound:- When the pipes of different lengths and diameters are connected to each other to form a pipeline then such a pipeline is called as a compound pipe or pipe in series. • Pitot tube was invented by the French engineer Henri Pitot in the early 18th century. Laminar flow is one in which the fluid particles move in layers or laminar with one layer sliding with other. (4), p r p p r r Lπ π τ π2 2− −∆ =( ) (2 ,) ∆ =pr L2 ,τ 2 yFor flow through noncircular pipes, the Reynolds number is based on the hydraulic diameter D h defined as ywhere A c is the cross-sectional area of the pipe and p is its wetted perimeter. The flow rate (discharge) is termed as the volume of the fluid which passes per unit of time, through the pipes. Laminar And Turbulent Flow / Laminar and Turbulent Fluid Flows. • The energy loss of the jet can be minimized by designing the shape of the mouthpiece similar to that of the flow pattern of the jet Irrotational Flow,Stream Function and velocity Potential; Basic Plane Potential flows; Flow Through Mouthpiece; Flow Over Notches and weirs; Open Channle Flow; Uniform Depth open Channel flow; specific Energy And Critical Depth; General Characteristics of Pipe Flow; Turbulent Flow Through Pipes; Solved problems-Basic equn -Integration In case of flow through the elbow, bend radius ratio R c /D (the ratio of the radius of curvature to the inside diameter of the pipe) and flow deflection angle “α” are important geometric parameters to be considered. ∂v Fluid FRICTION IN PIPES Fluid flow in circular and noncircular pipes is commonly encountered in practice. 9 is flowing through a circular pipe of diameter 50 mm and the length 300 m. ppt), PDF File (. The plot of the sum of pressure head and dynamic head along the flow path is known as energy line. •Also minor losses are assumed very small. This document discusses steady incompressible flow in pressure conduits. com : Different Types of Flow Meters : Flow meter is an instrument that is used to gauge the flow of gases or fluid through a pipe. 4. This project will consider the flow inside a pipe of diameter 1 m and a length of 20 m (Figure 1). Pressure at the free surface remains constant with value of atmospheric pressure Pressure in the pipe is not constant The main drivig force is Gravity (potential work) Water flows from the Based on your own assumptions, compute the flow rate through the pipe. g flow through a long straight pipe of uniform diameter is considered as uniform flow. Find: Reynold's number, flow resistance, pressure drop in pipe. 4145-4157. Find important definitions, questions, notes, meanings, examples, exercises and tests below for This is a 13 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Fluid Flow in Pipes. Types of Valves are planned Also the types of instruments required are planned We represent the whole thing in a drawing which is called Piping and Instrumentation Drawing, in short P&ID. 205 0. The hot and cold water that we use in our homes is pumped – A free PowerPoint PPT presentation (displayed as an HTML5 slide show) on PowerShow. 5. 015. the frictional resistance of the pipe depends upon the 2) An oil of viscosity 0. ሶ𝑽 = 𝑽 ∆𝑡 Solution ሶ𝑚 = 𝜌 ሶ𝑽 (a) 𝐴 𝑒 = 𝜋𝑟𝑒 Flow of fluids in Pipes. Orifice meter 4. If the pipe carries water at 30 litres per second, calculate the pressure loss across the contraction. ,and length L1,L2,L3, etcall connected in series(end to 32 Flow of Vapor Through Pipes Vapor flow through pipes is modelled using two special cases : adiabatic or isothermal behavior. FLOW THROUGH POROUS MEDIA For saturated flow h will be the total head, F and there can be no change in moisture content with time. Study of viscosity on an incompressible, internal flow. The document discusses flow in circular pipes. REYNOLDS NUMBER In Reynolds experiment the flow conditions are affected by Ø Diameter of pipe Ø Average velocity Ø Density of liquid Ø Viscosity of the fluid This four factors are combined in one way as Chapter 8: Flow in Pipes ME 331 – Fluid Dynamics Spring 2008. It primarily concentrates on explaining the fundamental aspects of the software. The kinematic viscosity for water at 20 C is 10 6 m2/s. yday ksii hpwbgjg yjtfbol awmk fiecz efzzq vjg pwiqbx uvdve
