A 400-V three-phase, wye-connected synchronous motor delivers 12 hp at the shaft and operates at 0.866 lagging power factor. The total iron, friction, and field copper losses are 1200 W. If the armature resistance is 0.75ohm per phase, determine the efficiency of the motor.
assume QPSK is the modulation method used in a digital communication system.The communication system requires minimum bit error.what is the acceptable bit error assuming additive white gaussian noise.
a. The mass of an electric car is 900 kg including the passengers. A single motor mounted on the front wheels drives the car, and the radius of the wheel is 0.3 m. The car is going downhill at a speed of 50 km/hr, and the slope of the hill is 30 d..
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss at ..
A half wave dipole antenna is operating in air at a frequency of 100 MHz. At a distance of 1000 km and at an observation point ? = ?/2, electric field strength is measured to be 5 µV/m. Calculate the a. Length of the antenna
2.25 kg of a fluid having a volume of 0.1 m^3 are contained in a cylinder at constant pressure of 7 bar. Heat energy is supplied to the fluid until the volume becomes 0.2 m^3. If the initial and final specific enthalpies of the fluid are 210 kj/kg..
Semiconductor A has a bandgap of 2.5eV while semiconductor B has a bandgap of 1.5eV. What is the ratio of the intrinsic carrier concentrations in the two materials (niA/niB) at 300K
If a system has a unit-impulse-response of h(t) = 100t * e^(-20t) u(t) , where u(t) is the standard unit step function, then determine the transfer function H(f) for the system. What type of filter is this system (high-pass, low-pass, band-pass, ..
