Complex Numbers : Solutions
www.cchem.berkeley.educomplex conjugate z∗ = a − 0i = a, which is also equal to z. So a real number is its own complex conjugate. [Suggestion : show this using Euler’s z = r eiθ representation of complex numbers.] Exercise 8. Take a point in the complex plane. In the Cartesian picture, how does the act of taking the complex conjugate move the point? What about in

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
Delta Functions - University of California, Berkeley
www.cchem.berkeley.eduExercise 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
