Flow Tubes hove many other plus values -- they're ccmpoct, compora* lively fight weight, and are easy to Install since they require minimum stroight runs entering and following. And, Flow Tubes are available In types and O/d ratios to provide differentials (hat can be accurately measured with the least head loss. That's why Flow Tubes are being successfully used In scores of Instol* lotions metering the flow of liquids and wet or dry gases. Available in all pipe sices and suitoble motols.

A constant effort is made to realise the use of genenl methods of analysis rather than Isolated procedures lot solving particular problems. To simplify presentation and analysis, ' the authors have avoided using the partial derivative In the mathematical treatment ef the aubjecL Omission of the mere complet aspects of the subject, such aa Inherently . unsteady flow, tod restrietloa of problems to direct application of individual princi ples hat resulted in further staipllfieatiin.
