BEIJING—Horizontal loops in catheter tubing can reduce flow rate by nearly two-thirds, a study has shown. Investigators analyzed water flow through Foley catheters of different diameters with or ...

Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers). Reasons for ...

Once pulverized coal flows have been measured, they can be balanced and optimized. Until then, tuning is simply guesswork. The right way to balance furnace fuel flows is to establish solid baseline ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

New research has improved control of slack line flow in steep slope liquids pipelines, whether during commissioning, steady operations, or in the wake of an accident. New research has improved control ...

Neil Hannay reports on the investigation and resolution of calibration limitations experienced during flowmeter development ...
