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 ...
Both the Cockcroft–Gault and the Modification of Diet in Renal Disease (MDRD) equations are used to guide adjustment of medication dose according to renal function. Neither equation has been validated ...
