A 3-phase load on a bus is metered at 3,200 kW with a 0.83 lagging power factor. What is the amount of capacitive reactive power that will correct the system power factor to 0.95? Draw all power triangles and show all variables, Q, P, S, pf.
In each of the three phases in a balanced delta- connected load is composed of a 10mF capacitor in parellel with a series-connected 470 ohm resistor and 4mH inductor combination, assume a phase voltage of 400 V at 50 Hz
There are three different beams and they asked us to choose which beam would you use to build an object that incurs high stress. Should I choose the beam with the lowest deflection or with the highest deflection
According to the Merriam-Webster dictionary, an invention is defined as something invented as a product of the imagination such as a device, contrivance, or process originated after study and experiment and an innovation is defined as the introduc..
An AISI 4140 OQT 1000 sleeve is to be secured to a 2.50-inch diameter solid rod ot the same material employing a class FN1 force fit. The outside diameter of the sleeve is 5.00 inches.
Along the way to the page, they pass into a region between two deflecting plates that are 1.6 cm long. There is a 1,500,000 N/C electric field between the deflecting plates. You measure the distance from the edge of the plates to the paper and fin..
Assume the initial state is unknown past with (z = 0). Implement the design in "Logicworks" and test for the properfunction. Use a binary switch to simulate the input. The output maybe implemented with a binary probe or an LED.
A p-n junction is made by doping Silicon with donors and acceptors. The doping at the p side has a uniform density of NA, but the doping density at the n side is not uniform and changes linearly with the distance from the metallurigical junction.
The amount of three phase power to be delivered in kW is equal to the total number of letters in your name (first name +last name) and the single phase power is 10% of three phase power. Assume same power factor for both types of loads.
A three phase motor draws 20kva at 0.7 lagging power factor from a 240 V source. Determine the kVAR rating of the capacitors to make the combined power factor 0.9 lagging and determine the line current before and after the capacitors are added.
The solution to Power Factor, Two single-phase loads are connected in parallel across a 415 V, 50 Hz supply. One load is rated 130 kW at a power factor of 0.75
Using Logisim, implement a 3-8 Decoder, both with gate level components and a Decoder component. Use input pins to control the select line inputs, and LEDs for the output display.
