A factory has an electrical load of 1,800kW at a lagging power factor of 0.6. An additional variable power factor load is to be added to the factory. The new loaf will add 600kW to the real power load of the factory. The power factor of the added load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. The factory is fed from a line having an impedance of 0.02 + j0.16 O. The voltage at the factory is maintained at 480 V(rms). Find the average power loss in the line before and after the load is added. Find the magnitude of the voltage at the sending end of the line before and after the load is added.
Giiven point p( -2 6 3) and vector a=yax +(x+z)ay. Express p and a in cylin and spher cordinates.eval a and p in the cartesian,cylin,and spherical systeem
A 3-D printer lays down a semicircular arc of positively charged plastic with a radiusR = 3.5 cm, and a linear charge density of Lambda = +1.9 uC/m. After the printer has finished the arc, the stylus moves to the center of the arc.
A VSWR is measured along a transmission line to be 2. Find two values for the reflection coefficient ? Which of these values will correspond to ZL Zc
a. Given the random binary data sequence 0110001011, provide waveform sketches for (i) NRZ change and (ii)split phase. b.Demonstrate satisfactorily that the split phase waveform can be obtained from the NRZ waveform.
send the pattern 0x99 to Memory Location VAR2 and call the delay function one more time. Repeat this operation eight times using a for loop. Assume that the bus clock frequency is 24MHz. Write the delay using inline assembly language.
Write the equation for the voltage across the capacitor for all time t > 0 (that is, after the switch opens at t = 0). Assume that the switch has been closed a long time before t = 0 to determine the initial condition on the capacitor.
aluminum has the FCC crystal structure. Its atomic weight is 26.98g/mole, and its density is 2.70g/cm3. Determine the atomic radius of a single aluminum atom.
A separately excited dc motor turns at 1200rpm when the armature is connected to a 115V source. Calculate the armature voltage required so that the motor runs at 1500rpm.
Experiments have revealed that flow over the board is disturbed by the elements and that convection heat transfer is correlated by an expression of the form Nux = 0.4 Re0.85 Pr 1/3 . Estimate the surface temperature of the chip if it is dissipatin..
With the following Boolean equations sketch a Moore Machine J0= Q'0 and y J1= Q2 and y or Q0 and y' J2 = Q1 and Q0 and y' K0 = Q0 and y' K1 =Q'0 and y' or Q'2 and Q0 K2= Q2 and Q'0 Use J-k flip flops for the Moore Machine J and K represent the fli..
The balanced 60Hz waveform sample that we must modulate is the point where t=4.4ms. The DC voltage from rail to rail is 300V. assume the q axis and a axis are in same direction. The use of mathCAD is recommended.
