Nuclear Power, Why is It The Last Option in Most Countries? (wiht full report)
Steam enters an adiabatic nozzle at 3.5Mpa and 300C with a low velocity and leaves at 1.6Mpa and 250C at a rate of 0.4kg/s. If the surrounding is 10 at 100Kpa and 18C, find A) The exit velocity B)The 2Nd law efficiency
Write a matlab function to generate Gray coding matrix. The function has one input M where M=2^m and m is the number of bits per symbol. For example, if the function my_graycoding(4), the output should be
explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the precise mathematical definitions

A power amplifier employs an output stage whose gam vanes from 2 to 12 for various reasons. What is the gain of an ideal (non varying) amplIfier connected to drive it so that an overall gain with feedback of 100 ± 5% V/V can be achieved
A synchronous motor exited by 5 kV source has a synchronous reactance of 5 ohm .The motor is running without any mechanical load(the output real power is zero). Ignore all losses and calculate thr equavelent field voltage Ef that delivers 3 M VAr ..
A charged 100-pf capacitor has initial voltage across it of 10V. a 100kohm resistor is suddenly connected across the capacitor (at t=0) to discharge it. What is the magnitude of the instantaneous current at 20 usec?
The resistance of the field circuit of a shunt-excited dc generator is 200. When the output power of the generator is 100kW, the terminal voltage is 500V and the generated e.m.f is 525V.
A single phase cyclo converter with mid point configuration is used for obtaining an output frequency of 1/3 times the input frequeny.Turns ratio from primary to upper seconday is 1/1 and to lower secondary is 1/2.
Find out the voltage that must be applied to the high voltage winding in order to provide rated voltage at the load under full-load conditions at 0.80 lagging power factor.
The maximum radius a falling liquid drop can have without breaking apart is given by the equation: R = sqrt((sigma/gp)) where sigma is the liquid surface tension, g is the acceleration due to gravity, and p is the density of the liquid.
