In a steam plant where you work, the turbine develops 1000 kW. The heat supplied to the steam in the boiler is 2800 kJ/kg and the heat rejected by the steam to the cooling water in the condenser is 2100 kJ/kg. The feed-pump work required to pump the condensate back into the boiler is 5 kW. Calculate the steam flow rate in this problem
A silicon abrupt junction, approximated by a step junction, has a doping of NA= 5 x1015/cm3 and ND= 1015/cm3 and a cross-sectional area (A) of 10-4cm2. Assume the depletion approximation, VA=0, and ni=1010/cm3 to: a. Calculate Vbi.
What is the minimum number of bits required to represent each of the following decimal numbers: 10, 1000, 100,000, and 1,000,000?
Single pole amp. has an open loop gain 10^6 and open loop bandwidth of 10Hz. If the feedback factor =1, calculate the gain and bandwidth after the feedback
Select f and K so that the steady-state error to a ramp input is less than or equal to 25% of the input magnitude.Determine the percent overshoot for a step input for the design selected in part (b).Use MATLAB to plot y(t) for a step input R(s).
The 300-kg block is acted upon by a force P, pulling it as shown. P makes an angle of 36o with the horizontal. If the coefficient of sliding friction between the block and the floor is 0.35, determine the force required to start moving the block.
Use a modulation index of 50 percent and a sampling rate of 160 kHz. In this project, develop a coherent demodulation for the modulated signal. Assume there is no channel error.
Write a program that uses the rand_float functions developed to generating sequences of random floating-point values between 4 and 10. Then compare the computed mean and variance to the theoretical values computed.
Compare GBN, SR, and TCP(no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel)
An engineering firm consisting of 3 programmers and 6 circuit engineers. The employees are randomly assign to 3 teams of 3, labeled Group 1, Group 2, and Group 3. a) How many ways are there to assign the 9 employees to Groups 1, 2 & 3
What are the incremental savings that result from increasing the efficiency of a PV collector by 1% in terms of collector area and costs? Assume that the PV module represents about 50% of the total PV system cost.
Write a HCS12 assembly-language program that copies values from ARRAY1 to ARRAY2 until it copies 10 values, or a value in ARRAY1 that is equal to zero.
A link is transmitting 10 Mbps in a bandwidth of 10 MHz using 1 mW of power. (Box 1) What change will you do to double the data rate and why (Box 2) How can you use the link if the noise were larger than the signal
