An air-standard Otto cycle has a compression ration of 9. At the beggining of compression, p1=100 kPa and T1= 300K. The heat addition per unit mass of air is 1350kJ/Kg. Determine. a) the net work, in kJ of air. b) the thermal efficiency of the cycle. c) the mean effective pressure, in kPa. d) the maximum temperature in the cycle, in K.
Voltage, current, power, and stored energy of capacitor, Prior to t=0, a 100- uF capacitance is uncharged. Starting at t=0, the voltage across the capacitor is increased linearly with time to 100V
Discuss what is meant by line spectra and what information can be gathered from a line spectrum plot. Discuss the similarities and differences between the Fourier Transform and the Laplace Transform.
A random sample of 50 mathematics grades out of a total of 200 showed a mean of 75 and a standard deviation of 10. (a) What are the 95% confidence limits for estimates of the mean of the 200 grades
Determine the HV-side fuses needed to protect a 3x140kVA, 12470/208 YNyn0 distribution transformer bank. Show and explain step by step the procedure you employ to solve this question. Use the type K and type T fuse curves
Charges +Q and +3Q are separted by a distance 2m. A third charge is located such that the electrostatic system is in equilibrium. Find the location and kthe value of the third charge in terms of Q.
A linear-phase FIR filter should be designed with the ideal magnitude response shown in Figure 1 which represents an narrow band-pass filter. The lower cutoff frequency, fL , is 2,000 Hz, and higher cutoff frequency, fH , is 3,600 Hz.
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
1. Find the volume of a frustum of a pyramid with square base of side 17, square top of side 9 and height 14.2. The base of a solid is a circular disk with radius3. Parallel cross sections perpendicular to the base are squares.
The voltage and current at the terminals of an ideal element are 0, for t _ (minus equal) 0s. V(t) = 100(1-e^(-300t) V, i(t) = 15e^(-400t) mA. Find the maximun power absorbed by the element by the element at t = 10ms
