Part II covers some specific calculations and their formulas and has examples of how to do such calculations. The Appendix contains a set of charts, graphs, and other helpful tables
We begin with some results that we shall use when making friction loss calculations for steady, fully developed, incompressible, Newtonian flow through a straight circular pipe. Volumetric flow rate Q = π D. 2 V. 4. where D is the pipe diameter, and V is the average velocity. ρ. Reynolds Number: Re = DV = DV = 4 Q = 4 m .
Chapter 2 presents the basic principles of conservation of mass, momentum, and energy, and introduces the concepts of head loss and energy grade line. Chapter 3 presents the conventional head loss equation and characterizes the two sources of head loss—surface friction and induced turbulence.
Momentum Equation for Inertial Control Volume with Rectilinear Acceleration For a Newtonian fluid: Shear Stress = Where μ is the dynamic viscosity of the fluid.
The purpose of this paper is to describe the equations which govern the flow of compressible fluids through pipes. Particular emphasis is placed on those used within the natural gas industry in hopes that engineers within that industry can make knowledgeable decisions on how to model pipes.
The water level in the reservoir is 60 m above the factory. The pipe lining has roughness 0.5 mm. Minor losses due to valves and pipe fittings can be accommodated by a loss coefficient = 80. Calculate the minimum diameter of pipe required to convey a discharge of 0.3 m3 s−1.
24 Ιουλ 2024 · Use this pipe flow calculator to analyze the properties of water flowing in a gravity-fed system. You only need to know the diameter of the pipe, the material it's made of, its length, and the drop in height. We then apply the Hazen-Williams equation for you, which calculates the resulting velocity and discharge. Interested?
