The distillation column shown in the drawing is used to distill a binary mixture. Symbols x, y, and z denote mole fractions of the more volatile component, while B, D, R, and F represent molar flow rates. It is desired to control distillate composition y despite disturbances in feed flow rate F. All flow rates can be measured and manipulated with the exception of F, which can only be measured. A composition analyzer provides measurements of y.
(a) Propose a feedback control method and sketch the schematic diagram.
(b) Suggest a feedforward control method and sketch the schematic diagram.
Calculate wavenumber B and wave length λ. Sketch Wave At Z=0 and Z=λ/4, and λ/2. Determine Magnetic Field Intensity H.
The fermi energy level for a particular T = 300K is 6.25 eV. The electrons in this material follow the Fermi-Dirac distribution function. (a) Find the probability of an energy level at 6.50 eV being occupied by an electron.
on an oscilloscope grid, the vertical axis is set to 1V/division, and the horizontal (time) axis is set to 1 ms/division.The postion of the CRT trace has been adjusted so that zero volt(ground) corresponds to the horizontal line in the center ofth..
A group society project due tomorrow. It is about designing our own Utopia. My part of the assignment is about the governing body and answering the questions that follow after talking about the governing body. I would like someone to help me with thi..
Write a program to create a time delay of approximately 100 seconds by using program loops, assuming that the bus frequency is 24Mhz. What is the approximated delay. How can you make it more accurate.
Find the system transfer function of a causal LSI system whose impulse response is given byh[n] = (-0.5)^n-1 sin[0.5(n-2)]u[n-2] and express the result in positive powers of z. Hint: The transfer function is just the z-transform of impulse respon..

The starter motor on a car draws 75-A starting current, which lowers the batery voltage from 12.6 to 9.1 V. What would be the battery voltage if it were being charged at 30 A.
Wien Bridge Oscillator: Simulate the oscillator in Simulink with a gain block of 3.1 and a feedback transfer function of s/(1 + 3s + s2). Include a saturation element and limit the amplitude at 10v peak to peak.
A semiconductor, in thermal equilibrium, has a hole concentration of p0 = 2x1016 cm-3. The minority carrier life time = 3x10-7 s. (Assume, ni = 1010 cm-3)
Assume you are standing atop the Engineering Research Center, holding a ketchup-filled water balloon. The dean is walking by in a bright, clean white hat, soon to arrive right underneath your perch. And temptation strikes. And is irresistible.
consider two groups are students, where the first group has 7 women and 3 men and the second group has 5 women and 5 men. Agroup is selected randomly and then students in the selected group are randomly arranged.
