Consider unsteady diffusion across a membrane of thickness L. Initially, the concentration of solute in the membrane is zero. At time zero, the concentration at x=0 is raised to C0 and the concentration at x=L is maintained at zero.
(1) Write the Ficks second law applied to this problem (including initial and boundary conditions).
(2) Under what condition can you use the semi-infinite medium assumption to solve this diffusion problem?
Improve the controller designed in part by introducing a mechanism for the disturbance compensation at the plant input. Illustrate advantage of the improved controller by applying the fast varying piecewise constant reference input vector and sinu..
a) What are the FIVE requirements for synchronizing the alternator tot he grid b) What should happen once the synchronous alternator is synchronized At that very instant, what should happen if the above five conditions are met
The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage. Calculate the power angle if the network receives an inductive reactive power of 50 MVA.
A new semiconductor has Nc = 1019 /cm3 and Nv=5 x 1018, and Eg = 2eV. If it is doped with 1017 donors (fully ionized), calculate the electron, hole, and intrinsic carrier concentrations at 627K.
a 10uF capacitor is plugged into a 110v rms 60 hz voltage source with an ammeter in series. what is the rms value of the current through the capacitor?
Assume a CDMA system has only 4 walsh codes. If the mobile is assigned W4 and receives a data stream of 11011010, what is the output?
In class we saw an example of 'Beat note'. In this problem we consider a more general case. Let fc > 0, fd > 0 and define a signal x as.
A single-phase, half-wave SCR circuit is used to control the power consumption of an inductive load. The resistive component of the load is 5 Ohm. The source voltage is 120 V (rms). When the triggering angle is adjusted to 60 degrees
2.25 kg of a fluid having a volume of 0.1 m^3 are contained in a cylinder at constant pressure of 7 bar. Heat energy is supplied to the fluid until the volume becomes 0.2 m^3. If the initial and final specific enthalpies of the fluid are 210 kj/kg..
For a new product sales are expected to be 2,000 products in year 1, increasing by 1,000 products each subsequent year to 5,000 products in year 4. Two different manufacturing equipment options are available a) Up front equipment purchase cost of $..
Get digital still images and video sequences from the Internet, as needed. You can use color and/or gray-scale images. 2. Implement intra-frame DPCM . Start with a linear quantizer in the initial implementation.
