The last article in this series focused on several refrigerant flow problems. This article continues by looking at compressor inefficiencies, noncondensables, and high and low entering air ...

Cash-Flow Problems? Here’s What to Do and What to Avoid You can emerge with your business reputation intact if you keep everyone appropriately informed.

A new survey of small companies finds most owners report recurring cash flow problems—and many missed opportunity due to those—but do little to prepare for or avert them.

We develop fast algorithms for previously unstudied specially structured minimum cost flow problems that have applications in many areas, such as locomotive and airline scheduling, repositioning of ...

A study was undertaken to document peak flow and load conditions in treatment plants. Data were analyzed from 11 plants ranging from 0.01 to 1.75 $ {\rm m}^ {3}/ {\rm s}$. Equations were developed to ...

Load-sensing controls To ensure flow matches demand, hydraulics manufacturers fit control valves with pressure compensators that control flow rates or distribution. Two designs predominate.
