Think of a cake. When you put it in the oven, it starts off at a particular volume and then, an hour later, it has risen to perhaps double its size. It is obvious what has happened – the air bubbles ...

These five terms are: the pressure (P), volume (V), number of moles (n), a constant (R)—with a value of 8.3145 joules per kelvin-mole—and temperature (T). You can't understand the ideal gas law ...

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 ...
