A 50-kW 440-V 50-Hz two-pole induction motor has a slip of 6 percent when operating at full-load conditions. At full-load conditions, the friction and windage losses are 520 W, and the core losses are 500W. Find the following values for full-load conditions:
(a) The shaft speed nm
(b) The output power in watts
(c) The load torque t load in newton-meters
(d) The induced torque t ind in newton-meters
(e) The rotor frequency in hertz
Combinational and sequential Logic Design using CPLDs - Number systems and codes, Boolean Algebra, Logic gates and flip-flops
A quartz window of thickness L serves as a viewing port in a furnace used for annealing steel. The inner surface (x = 0) of the window is irradiated with a uniform heat flux q;: due to emission from hot gases in the furnace.
Design first order and high-pass filter that has a gain of 10 and corner frequency of 0.05Hz. Verify your design using transfer function and frequency response.
a nonconducting circular disk of radius r carries a uniformly distributed electric charge q. the plate is set
a)Write the diffrenece equation for a four-term moving average filter. b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
In a certain system, an electrical heating element was found to increase the temperature of a piece of metal 7o for each amp of current. The metal expands 0.004 in./deg and pushes on a load sensor that outputs 1 V/0.003 in.
consider a sinusoidal wave with frequency of 300khz as a carrier signal. we want to transmit a sinusoidal signal with
A certain type of power resistor comes in the following rating:3w,5w,8w,12w,20w. your particular application requires a resistor that can handle approximately 8w.
The unit impulse response of the system - Find the first three terms of the causal signal - calculate the electric field E from Gauss law and then obtain the potential at the center of the charge distribution
A laser beam traveling through fog was obseved to have an intensity of 1w/m^2 at a distance of 2 meters and intensity of 0.2 w/m^2 at a distance of 3 meters. Knowing that the intensity of an Electromagnetic wave is proportionel to the square of it..
Two input voltages are v1(t) and v2(??). Design an op-amp circuit that will generate the voltage 3v1(??) - 2??2(??). Its input resistance must exceed 1 kΩ and its output resistance must be less than 10 Ω. Use more than one op-amp if necess..
Design an op-amp astable multivibrator to have an output frequency of 400Hz and the frequency should be adjustable by plus or minus 20%. Use a 741 op-amp with supply of plus or minus 18 volts.
