A Python script model was created to calculate HOG for any given distillate and flow rate, and the HOG could be compared against vapor velocity to find the optimal operating conditions. They are also known as regulators and are used in a wide variety of applications. Orifices and nozzles are typically used to deliberately reduce pressure, restrict flow or to measure flow rate. As you can see, while relative humidity might be a useful benchmark for weather reporting, dew point is the parameter of choice when one is concerned about condensation in a gas sample to be analyzed—especially one coming from a process stack. In this function f(a,b), a and b are called positional arguments, and they are required, and must be provided in the same order as the function defines. It may represent a safety hazard, or an opportunity depending on the process.
