Problem #1 :

Using separation of variables and the formalism demonstrated in class, find the general solution to the Helmholtz equation (also known as the time independent wave equation) :

∇^2 F + k^2 F = 0

Assume that k is a real number. For clarification, the general solution is the solution in the case where boundary conditions are not specified.

Problem #2 :

Express the following functions as an infinite Fourier sine series using sin(nπx/a)

a)f(x) = x

b)f(x) = e^x

c)f(x) = cos(x)

Using C# Create the “TestQuestion” class. It will have two class variables: 1) a question and 2) the answer to that question. Please create an accessor and mutator method for both of those variables, without which we would not be able to see or change the question or the answer. There should be a constructor method. We will also have a “ToString” or “__str__” method, which will print the question followed by its answer. The constructor method has two parameters...

Separation Process: Consider the in-class demonstration problem involving the MeOH/water separation. Suppose that a saturated steam feed was injected into the bottom of column (it is sparged to get good contact with the liquid that is falling down from the tray above its entrance). Take the specifications for the feed to be identical as in the McCabe-Thiele demonstration done in class (zF = 0.36, F = 216.8 kmol/h). Further, the compositions of the distillate and the bottoms should be the...

Use the separation of variables method to solve the following problem. Consider a long, narrow tube connecting two large, well-mixed reservoirs containing a small concentration of N2 in another inert gas. The tube length is L = 100 cm. To establish an initial concentration profile in the tube, each reservoir is held at a fixed concentration: Reservoir 1 contains no N2 and reservoir 2 has 2 × 10−6 mol/cm3 of N2. (a) At t = 0, the concentrations of the...
