Delta Functions - University of California, Berkeley
Exercise 2.1. Using the definition of a Dirac Delta function given in equation (9), prove that the Dirac Delta function has to be normalized. i.e. prove: Z ∞ −∞ δ(x)dx = 1 Another way that you can think of the Dirac Delta function is as the deriva-tive of the step (Heaviside) function, H(x). This function looks like: x 0 x H(x) y 1

Flammable Liquids and Solids
www.cchem.berkeley.eduFlammable and combustible liquids are defined by their flash point. Flammable liquids are divided into 4 categories: • Category 1 includes liquids having flashpoints below 73.4 °F (23 °C) and having a boiling point at or below 95 °F (35 °C) • Category 2 includes liquids having flashpoints below 73.4 °F (23 °C) and having a boiling point

Don’t Gamble With Physical Properties For Simulations
www.cchem.berkeley.eduVapor enthalpy usually is calculated via an ideal gas assumption or an equation of state. The equation-of-state methods calculate a depar-ture from ideality called the vapor enthalpy departure. For components such as acetic acid, the Hayden-O’Connell model is best, and will calcu-late a larger-than-normal vapor enthalpy departure.
Visualizing the McCabe-Thiele Diagram
www.cchem.berkeley.eduThe McCabe-Thiele diagram is constructed by “stepping off stages.” The starting point is (x D, x D), which is the vapor composition ascending from tray 1. The liquid composition descending from tray 1 is the mole fraction in equilibrium with a vapor with composition x D

In the Cartesian picture, how does the act of taking the complex conjugate move the point? What about in
