1. Two immiscible fluids of different density and viscosity are flowing between two parallel plates. Express the boundary conditions at the interface between the two fluids.
2. Determine the velocity profile for fluid flowing between two parallel plates separated by a distance 2h. The pressure drop is constant.
The turbine has a variable tip speed ratio (TSR). At a wind speed of 10m/s, compute the minimum TSR of the wind turbine.
What is the smallest number of samples that could be collected in order to know for sure whether or not the 1000Hz component is present? Assume you are using a Rectangular window.
Plot the impedance of the network versus frequency from 0 to 10 kHz. - Plot the current i versus frequency for the frequency range zero to 10 kHz.
A FIR filter is depicted in the figure below. Assume that the system is at rest and an input sequence is applied to the system. Determine the first seven samples of the system output Assume that the system is initially at rest. x(n)=u(n)+u(n-1)-2u..
If the signal is connected to the input of an inverting op-amp circuit, what voltage gain is necessary so that the output of the amplifier produces a change of 2 V for every degree change in temperature
A computer has a 32-bit instruction word broken into fields as follows: opcode, six bits; two register fields, five bits each; and one immediate operand/register field, 16 bits (a) What is the maximum number of operations that can be specified
What is the information associated with the drawing of a pair of cards, assuming that the first card drawn is replaced in the deck prior to drawing the second card?
Simulate the voltage-doubler rectifier circuit in Fig. P3.101 for C = 500 F and vI = 1500 sin 2π(60)t with a load resistance of RL = 3000 Ω added between vO and ground. Calculate the ripple voltage and compare to the simulation.
Consider a 16-ary PSK system with symbol error probability PE = 10-5. A Gray code is used for the symbol to bit assignment. What is the approximate bit error probability
A M-bit thermometer code for the number k consists of k 1's in the least significant bit positions and M-k 0's in the more significant bit positions. A binary-to-thermometer code converter has N inputs and 2^N-1 outputs.
Suppose you want to build a simple RS flip-flop that is set and reset by negativegoing pulses. All you have are two 2-input AND's and two 2-input NOR's. Show how you would build this odd circuit from the available material.
It is desired to transmit data at 9 kbps over a channel of bandwidth 7 kHz using raised-cosine pulses. What is the maximum value of the roll-off factor ß that can be used?
