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 ...

A method has been developed that allows direct, accurate calculation of recovery efficiency for Claus sulfur-recovery units (SRU). The calculation combines feed-gas data and tail-gas composition to ...

Often in algebra we have an equation that we want to solve. This frequently involves manipulating the equation in various different ways to achieve a desired outcome. Key fact The golden rule when ...

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...
