Assume that one of the pumps uses a1/4hp DC shunt motor with an input voltage of 115VDC that pulls 1.6A running at 1500 rpm. The filed resistance for the motor is 600 ohms and the armature resistance is 8.5 ohms. Find the constant KT for this motor.
Develop a functional design for a system that measures and displays the speed of a bicycle. Be sure to clearly identify the design levels, function requirements, and theory of operation for each level.
what single amount at the end of seven years is equivalent to a uniform annual series of %5000 per year for 12 years if the interest rate is 8% compounded annually
An MFSK modulation scheme with M = 4has a carrier frequency of 250 kHz, a difference frequency of 25 kHz, and two bits per signal element. Make a frequency assignment for each of the possible data combinations.
Draw a circuit diagram to show how the CT, VT and meters are connected into the load circuit. Neglecting instrument and transformer errors, calculate the load kVA and power factor if the voltmeter, ammeter and wattmeter indicate values of 200 V, 2..
Let E = yax V/m at a certain instant of time, and calculate the work required to move a 3-C charge from (1,3,5) to (2,0,3) along the straight-line segments joining: a) (1,3,5) to (2,3,5) to (2,0,5) to (2,0,3) b) (1,3,5) to (1,3,3) to (1,0,3) to (2,..
A circular capacitor of radius r is made using SiO2 as the dielectric on a silicon wafer. If a trench of depth l is made to replace the circular capacitor with the trench capacitor with trench depth l, find the ratio of the two capacitances.
Develop the pseudo-code below for a program that will retrieve 2 bytes (NUM1 and NUM2) from memory, determine which is closest to the numeric value 50, and indicate the result by setting a variable named "CLOSEST" to 1 (if 1st byte is closest) or ..
Describe whether Google is exploitive, impoverished, supportive, or enlightened. Describe the features google that indicate which kind of organization it is. Describe five steps google could take to become better and move up in the scale.
Consider an industrial load that absorbs 40 kW of power with power factor 0.8 lagging from a 60-Hz transmission line of voltage VL= 240
How would you know a system is linear by just looking at its input/output characteristic graph And what does the sensitivity of a sensor tells us about the sensor
The lighting and motor loads of a small factory establish a 10kVA power demand at 0.7 lagging power factor on a 208V, 60 Hz supply. Determine the power-factor capacitor that must be placed in parallel
A three-stage amplifier is shown. The operating bandwidth is 500 KHz at a temperature od 25 degrees C. The output load is 1000 ohms. calculate the total NF as a number, calculate the output noise power, and calculate the output noise voltage.
