A graph that shows the vapor-liquid equilibrium relationship of two components is called an xy diagram. xy diagram means that the vapor-liquid equilibrium composition of the two components at a certain temperature and pressure will be the value on the vapor-liquid equilibrium curve, and the vapor-liquid equilibrium curve is obtained and used in the design of the distillation column.

Bernoulli's principle：Basic formula for pump head calculation
2022/1/19
The energy conservation law for fluids is called Bernoulli's principle in particular. Thanks to Bernoulli's principle, engineers can calculate how much energy and pump lift is needed to lift a fluid to a given height.
