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 ...

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 ...

A new empirical correlation can help engineers size chokes for controlling gas-condensate production and predicting the performance of flowing wells under different conditions. The correlation was ...
