Chapter 20, Problem 28QAP

You and your crew have made it through the night and the day has brought more warmth.  After searching the industrial site, you find an abundant amount of fuel to run the generators to keep you warm.  You also find a memory card labelled “cure”, but your cell phone battery is dead.  First things first, you will need to stay safe as the zombies continue to hunt you in your current location.  The industrial site is surrounded by a metal chain-link fence.  You decide you will electrify the fence to keep the zombies from scaling it.  But the output voltage from the generators is not high enough to really deter them.  You would like to apply around 10 kV to the fence (AC or DC, at that voltage it doesn’t really matter).  You find a transformer that you can use but it only has a turn ratio of 10.  You find some diodes and capacitors and construct the circuit shown in Figure 3 with the intention of hooking Vout to the fence.   Perform a simulation, displaying the voltage Vout using a scope.…

Part F: Progressive activity week 7 Q.F1 Pick the rural location of a project site in Victoria, and its catchment area-not bigger than 25 sqkm, and given the below information, determine the rainfall intensity for ARI 5, 50, 100 year storm event. Show all the details of the procedure. Each student must propose different length of streams and elevations. Use fig below as a sample only. Pt. E-nt 950 200 P: D-40, PC-92.0 300m 300m 000m PL.-02.0 500m HI-MAGO PLA-M 91.00 To be deemed satisfactory the solution must include: Q.F1.1.Choice of catchment location Q.F1.2. A sketch displaying length of stream and elevation Q.F1.3. Catchment's IFD obtained from the Buro of Metheorology for specified ARI Q.F1.4.Calculation of the time of concentration-this must include a detailed determination of the equivalent slope. Q.F1.5.Use must be made of the Bransby-Williams method for the determination of the equivalent slope. Q.F1.6.The graphical display of the estimation of intensities for ARI 5,50, 100…

It is the middle of a winter snowstorm. Sally and Jin take shelter under an overhang. The loading of the snow on top of the overhang is shown in the figure below. The overhang is attached to the wall at points A and B with pin supports.  Another pin is at C. Determine the reactions of the pin supports at A and B. Express them in Cartesian vector form.

Please answer all questions 1. Calculate the magnitude (in RMS) of the current through R1 2. Calculate the magnitude (in RMS) of the current through R2. Simulation  1. Construct the circuit in Figure 2 in the Circuit JS simulator. Note that transformers in Circuit JS may be unstable. It is suggested to draw them by clicking from the bottom left corner to the top right corner and refresh your simulation before taking a measurement. 2. Perform a simulation, displaying the voltage across the voltage source, the current through R1, and the current through R2 in a “stacked” scope.  Display the RMS average for each trace. Include a screenshot.  Analysis 1. Compare the simulation results for the currents through R1 and R2. What is the percentage difference between the calculated and simulated value for each? Comment on why there may be a discrepancy.

2. A three-phase transformer connection Yy, 2000 kVA, 20000/6000 V has the relative short-circuit voltages Ecc = 7% and ERcc = 1.7%.It is known that when empty this transformer consumes a power Po = 12.24 kW. Calculate:a. Parameters Zcc, Rcc, Xcc, referring to the primary and EXcc.b. If the transformer is connected at rated voltage and feeds a load of 1800 kVA, fp = 0.8, calculate the line voltage at the secondary.c. The maximum apparent power, and the maximum efficiency fp = 0.8 inductive.   Perform the exercise by the collaborators and without using artificial intelligence please

A nozzle is attached to a fire hose by a bolted flange as shown below. What is the force tending to tear apart that flange when the valve in the nozzle is closed?

1. A three-phase transformer with Yd connection, 300 kVA, 12000/220 V, has been short-circuit tested on the high voltage side giving the following results: 750 V, 14.434 A, 10838 W.When the transformer is connected to nominal voltage without load it consumes 5400W. Calculate:to. Relative voltages of short circuit high voltage side: εcc, εRcc and εXcc.b. The voltage in the secondary when the transformer is connected to nominal voltage and feeds a load of 200 kW fp = 0.8 in delay.c. Apparent power of maximum efficiency and maximum efficiency with fp = 0.95 inductive.   Please solve for one of the collaborators and without using artificial intelligence
