If the shock-wave velocity in Problem is approximated by the speed of sound, determine the pressure change causing a velocity change of 10 fps in(a) air at standard conditions;
(b) water.
Problem:-The shock wave illustrated below is moving to the right at vw fps. The properties in front and in back of the shock are not a function of time. By using the illustrated control volume, show that the pressure difference across the shock isP2 - P1 = Ρ1vwv2
The full-load speed is 1750 rpm. Under no-load conditions, the speed is 1797 rpm, and the line current is 6.5A rms at a power factor of 30 percent lagging. Find the power loss and efficiency with full load, the input power with no load, and the sp..
Design an air-filled C-band (5-8 GHz) rectangular waveguide such that the center frequency of this band (f= 6 GHz) is at least 25% higher than the cutoff frequency of the TE10 mode and at least 25% lower than the cutoff frequency of the next highe..
Write the theoretical Power Spectral Density for a BPSK signal with shift angle of 180 degrees, carrier of 25 kHz and bit rate of about 1 kHz that has been spread by a PN sequence with a bit rate of about 100 kHz. State it or derive it.
when operating in the step down mode and feeding a load impedance of 8
calculate the maximum power that can be sent through an a2cm b1cm air-filled waveguide at 12 ghz such that
The time t required to test a computer memory unit is directly proportional to the square of the number n of memory cells in the unit. For particular type of unit, n= 6400 for t= 25.0s. Find the instantaneous rate of change t with respect to n for..
A 1 MVA three-phase 6,600/400V delta/star connected transformer has the following parameters per phase. Calculate the per unit impedance of the transformer using base values of 1 MVA and 400 V.
A discrete-time signal x[n] is periodic with period 8. One period of its DFT harmonic function is {X[0],...,X[7]}={3,4+ j5,- 4 - j3,1+ j5,- 4,1- j5,- 4 + j3,4 - j5}. (a) What is the average value of x[n] (b) What is the signal power of x[n]
A dc motor is driving a constant-torque load. If the armature voltage of the motor increases by 20%, calculate the percentage change in no load speed.
Consider the Go-back N scheme with window size N = 2 and assume that 2 bits are used for the sequence number field. The sender has four packets (labeled A, B, C and D) to send to the receiver. Suppose that packet C is lost the first time that the s..
There are 5280 feet per mile. There are 3 feet in a yard. Use appropriate parameter passing and return mechanisms. Use appropriate datatypes. For example, with inputs of 1760 yards and 1320 ft, the result would be 1.25 miles.
An 8.0 mm (0.31 in.) diameter cylindrical rod fabricated from a red brass alloy (Figure) is subjected to reversed tension-compression load cycling along its axis. If the maximum tensile and compressive loads are +7500 N (1700lbf) and -7500 N (-170..
