A 100 hp, 3 phase induction motor, operating at the rated load, runs at 423 rpm when connected across a 450 V, 60Hz supply. The slip at this load is 0.06. Determine
A). Synchronous Speed
B). Number of stator poles
C). rotor frequency
Water is the working fluid in a vapor power cycle with reheat, superheat and reheat. Superheated steam enters the first turbine stage at 8 MPa, 480 C and expands to 0.7 MPa
Consider the following differential equation, where x(t) is the input and y(t) is the output: d/dt y(t)+5y(t)=2x(t) Suppose the input is x(t) = 4u(t) and the initial condition is y(0-) = 6 1. What is the impulse response for the system
Explain the operation of sequential logic devices and evaluate the output waveform in relation to the clock for QA, QB and QC in the subsequent circuit and show the binary sequence represented by these waveforms
a) The input of Hex- to - seven segment decoder is 1010. what will the display show. b) A priority encoder has all inputs activated. Which input will be encoded. Why.
Discuss the different analog-to-digital converter (ADC) types and configurations. What is the purpose of the ADC. How do you interface to the different configuration
A wind speed sensor generates an output voltage that ranges between 10 to 55 mV when the wind speed varies from 0 to 120Km/Hr.The output of the sensor is connected to an Analog to Digital Converter (ADC) through a signal conditioning circuit.
List three standard socket calls that you would expect every connection-oriented server to invoke that would not normally be invoked by any client. Briefy indicate why a typical client would not need to invoke these calls.
An absolute optical rotary encoder has five tracks. How many bits is the output, and what is the resolution in degrees per state (that is, degrees per LSB)
In a 50 KVA, Y connected, 440 V, 3 phase, 50 Hz alternator, the effective armature resistance is 0.25 ohms per phase. Synchronous reactance is 3.2 ohms per phase. Determine at rated load and unity power factor,
A flood control project with a life of 12 years will require an investment of $300,000 and annual maintenance costs of $25,000. The project will provide no benefits for the first two years but will save $40,000 per year in flood damage
Design a Moore machine that has one input X and one output Z. Provide a complete design using D Flip flops. In this design, the output should be 1 any time the sequence 01101 occurs. Overlapping sequences are allowed.
A HCS12 ATD is set to 10-bit unsigned mode. The voltage references are set to ground and 1.0V What is the ADT output for a temperature of 81 degrees The temperature sensor measures 0 to 100 degrees with an output of 10 mV/degree.
