Several kinds of pipe flow calculations can be made with the Darcy-Weisbach equation and the Moody friction factor. These calculations can be conveniently carried out with an Excel spreadsheet. Many of the calculations require an iterative solution, so they are especially suitable for an Excel spreadsheet solution.

Resistance to change. As the air enters the ductwork system – in Figure 3 through a simple louvred entry – the air will be accelerated from the still air outside the louvre to a velocity determined by the volume flowrate, q v (m 3 /s) of the air, and the area, A (m 2) of the this case as. orifice size and flow calculations.

There may also be a pressure gain/loss due a change in elevation between the start and end of the pipe. The program includes 2 procedures placed on customized command bar use to know the value of the coefficient K. 1° / - Module of imputation on the working sheet of the designation and the value of the K-factor.
2°/ - Data Visualization Module of the pressure loss coefficients according to the duct shape. In the case of oblong ducts. With every calculator, you can read the full theoretical explanation and check calculation formulas.
Fluid properties tables are available as well as dimensions of standard pipes. More than K calculations per year. Used every day by thousands of students and professionals.
Other Meter Types Other devices that have applications in flow measurement include swirlmeters and rotameters. Permanent Pressure Loss The amount of unrecovered loss due to a flow. 15–5 Compressible Flow CFD Calculations Compressible Flow through a Converging–Diverging Nozzle Oblique Shocks over a Wedge.
Pipe Flow Calculations. Shankar Subramanian. Department of Chemical and Biomolecular Engineering. Clarkson University. We begin with some results that we shall use when making friction loss calculations for steady, fully developed, incompressible, Newtonian flow through a File Size: KB. Many manufactures of control valves choose to publish a Cv flow coefficient or a Kv flow coefficient to describe the flow / pressure loss characteristics of their control valves in a standardized manner.
A Cv flow coefficient specifies the amount of water at 60°F ( °C) in US gpm that will flow through a valve and produce a psi. Isentropic flows occur when the change in flow variables is small and gradual, such as the ideal flow through the nozzle shown above. The generation of sound waves is an isentropic process.
A supersonic flow that is turned while the flow area increases is also isentropic. We call this an isentropic expansion because of.
Confusion in the use of the terms tatic “S Pressure”, “Velocity Pressure” and “Total Pressure” is widely prevalent among HVAC ngineers and e contractors.
The term “Static Pressure” is typically used for fan selection; “Velocity Pressure” is used for. Fan Affinity Laws Calculator - Changing Wheel Velocity. Replace the default values with the actual values. The calculator is generic and can be used with all common units as long as the units use is consistent.
q 1 - volume capacity - (m 3 /s, gpm, cfm.) dp 1 - head or pressure (m, ft, Pa, psi.). Full text of "Fundamentals of compressible Flow" See other formats. If the pressure drop is between 10% and 40% of the upstream gage pressure, then the density should be based on the average of the upstream and downstream conditions.
If the pressure drop exceeds 40% of the upstream gage pressure, then a compressible pipe flow model, like the Weymouth, Panhandle A, or Panhandle B should be used. Pipe Flow Scenarios. The effective efficiency of the SAH was 32 ± 5% at the airflow between kg/s and kg/s, 42 ± 6% at the airflow ranging from kg/s to kg/s, and 46 ± 11% at the airflow of 0.
It is the use of fluid thermodynamic data and the thermodynamic principles of the “constant enthalpy throttling process” that throttling valves experience which allows an accurate determi- nation of a fluid’s state while internal to the valve as well as at the valve’s outlet.

This book is very popular for Mechanical engineering student for use of As Reference book, GATE Preparation, Competitive exam Preparation, Campus. Actual cubic feet per minute (ACFM) is a unit of volumetric flow.
It is commonly used by manufacturers of blowers and is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.
Suppose steam at MPa, °C is to be expanded through a converging nozzle under choked flow conditions. Use Eq. () to calculate T * and use the steam tables (or Mollier diagram or computer program) with this value of T * and s * = s os to find p * and ρ * = 1/v *.
Then compare these values with the ones calculated from Eqs. Thrust is directly dependent on engine airflow while aircraft drag is independent of the airflow* but is a function of flight * Airflow variation can have a minor effect on the aft end drag due to expansion of the jet stream outside of the nozzle which can produce a supersonic shock on the fuselage IIA annulus, and away from bends and Author: W.B.
Briggs.This book – the first of its kind – covers ab initio the aerodynamics of subsonic and supersonic intakes in civil and military types of aircraft. The problems of both internal and external airflow are investigated. The contents and style of presentation will have a wide appeal.
