Carry out the preliminary design of a closed domestic hot water heater that has a first law efficiency of at least 95.0% and a second law efficiency of at least 10.0%.
The inlet water temperature is fixed at 10.0°C. The remaining variables (including the ground state) are unrestrained and can be chosen to fit the needs of the designer.
Explain why an orifice plate meter is suitable for this application.- Estimate the required orifice plate hole diameter if the transmitter has an input range of 0 to 1.25 x 104 Pa.
A 5-volt intelligence amplitude causes the frequency to change to ± 25 kHz. What will be the carrier frequency variation corresponding to an intelligence amplitude of 10 volts.
The frequencies of the tones are 100 Hz, 300 Hz, and 450 Hz. The sampling rate is 1 kHz. Describe a low pass, a band pass, and a high pass filter that could be used to detect the individual tones.
Obtain the optimum tap weights for a three-tap MMSE equalizer and at a SNR of 10 dB and b = 0:5.
If a signal plus noise is fed into a linear device, show that the noise figure of that device is given by F = (S/N)in(S/N)out (Hint: Start with the basic definition of noise figure that is given in this chapter.)
A CMOS output driver circuit on an IC is connected to an external transmission line. The NMOS and PMOS transistors have gate oxide thickness d = 2.0 nm and channel length L = 0.25 mum. The power rail is VDO = 1.0 V.
Identify three test cases, one using a number with 4 factors, one using a negative number, and one using a number with more than 4 factors. For each of the three test cases show what inputs you will use and what your expected outputs should be.
What is the highest frequency of a triangle wave of 20V peak-to-peak amplitude that can be reproduced by an op amp whose slew rate is 10v/s. For a sine wave of the same frequency.
The fluid travels through a conduit of negligible resistance; an accumulator is included to smooth out the pulsations of the pump. A hydraulic load (modeled by a fluid resistance R) is connected between a pipe and a reservoir (assumed at zero pres..
How do financial institutions help with risk-bearing?
Consider a 4-bit counter made with JK flip-flops with preset and clear inputs. Describe the changes/additions that need to make the counter reset after counting to 1001. Be sure to state any assumptions that are made.
Determine the range of vO1 for which both N1 and P1 are biased in the saturation region. - If vO2 = 0.6 V, determine the values of vO3, vO1, and vI.
