A chemical plant needs a microprocessor-driven alarm system to warn of critical conditions in one of its chemical tanks. The thank has four HIGH/LOW (1/0) switches that monitor temperature(T), pressure (P), fluid (F), and weight (W). The alarm (A)will activate when any of the following conditions are met
1. High fluid level, high temperature, high pressure.2. low fluid level, high temperature, high weight.3. low fluid level,low temperature, high pressure.4. low fluid level, low weight, high temperature.
A) Show the truth table of this function.B) Write the logic equation for this function. DO NOTsimplify the equation.
Vs=310 V (Vrms=219 V) at the input of bridge rectifier Need LC filter at the output of bridge which can provide 240 V +-10V DC, with 2 A constant current. find method to find appropriate values of LC which can provide these specification.
A separately excited dc motor turns at 1200rpm when the armature is connected to a 115V source. Calculate the armature voltage required so that the motor runs at 1500rpm.
What is the minimum donor doping required to convert Silicon into a conductor? What is the minimum acceptor doping required to convert Silicon into a conductor?
In region 1, defined by z>0, there is a magnetic field of H= 4.8x ˆ 6y ˆ +8z (A/m) and the relative permeability is 50. Determine the magnetic flux density B in region 2, z
write a script that will call: a function to prompt the user for an angle in degrees and call a function to calculate and return the angle in radians (note:pi radian =180) and call a function to print the result.
In a 60-HZ, 208 V (line-line, rms), 5-kW motor, R'r = 0.45Ω and X'tr = 0.83Ω. The rated torque is developed at the slip s = 0.04. Assuming that the motor is supplied with rated voltages and is delivering the rated torque,
