Overview Here's Why the BIF® UVT's are Superior BIF UVT's Provide High Accuracy with Energy Efficient Design and Operation Mathematical Definitions Basic Hydraulics of Flow Metering Mathematical Definitions Thermodynamic Properties (Gases Only) = ratio of specific heat at constant pressure to specific heat at constant volume. [ = 1.3 for steam and 1.4 for air] Z = Supercompressibility Factor - a factor to equate a real gas to an ideal gas. Z = 1 for steam and for air above 0 psia and 0 F. Flow Properties The Reynolds Number (RD) is the ratio of inertia forces of a flowing medium to the shear forces. This number is important because it relates two geometrically similar flows. That is, it can relate flows at high velocities in small pipes to flows at low velocities in large pipes. Its value is an indication of the type of flow: RD less than 2000 implies laminar flow RD greater than 7000 implies turbulent flow and the operating range for Venturii General Formula for pipe flow: Practical formulas: Copyright © 1997 BIF Comments regarding this site, please contact webmaster@intersoftgroup.com Site created by Jon'taar Graphxs
