Consumer surplus is the amount exceeding an equilibrium price the consumer is willing to pay. The equilibrium price is an idealized price, in which the demand for the good equals its supply. If the ...

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 ...

THE “simplified” method of calculating a linear regression put forward by Aldridge, Berry and Davies 1 is the well-known method of orthogonal polynomials which was put on a practical working basis by ...

Collapse-resistance values for special casing that undergoes external deformation can be calculated with new pressure equations developed by the Southwest Petroleum Institute, China. These equations ...
