A 100 kw, 240 V shunt generator has a field resistance of 55 Ohm and armature resistance of 0.067 Ohm.
Find the full load generated voltage.
1- Derive the transfer function of a third orderlow Pass Butterworth filter for a bandwidth of200 rad/sec. 2-Draw a simulation diagram for the design of this filter. Use integrators, amplifiers and summers.
one side of an oxygen meter is exposed to oxygen in equilibrium with a mixture of Ni and NiO at 1300K, and the other side is exposed to air at 101kPa. If the cell e.m.f is 0.596V, Calculate the standard free energy change at 1300K for the reaction..
In a PCM system, the number of quantization levels is 16 and the maximum lsignal frequency is 4 kHz.;what is the bit transmission rate.
The local building regulations prohibits construction of buildings higher than 25 m. Determine if it is possible to mount the antennas right at the roof top or if antenna masts to raise the height are needed. In the later case, what should the hei..
Flux weakening causes problems in both generators and motors. In generators, the effect of flux weakening is simply to reduce the voltage supplied by the generator for any given load. In motors, the effect can be more serious.
Calculate the number of free electrons per cubic centimeter in copper, assuming that the maximum energy of these electrons equals the Fenni energy (m* = mol.)
How to Testing Electrical and Electronics Components and Devices with Multimeter ?
A three phase 4.157kv 60hz power system serves a 2880kva load pf=.8 lagging. Draw the ac equivalent circuit with load impedance element equated. The load is delta connected. solve for all the current (6 total).
Two coils A and B are mutually coupled so that 55% of the flux of Coil A links Coil B. It is found that current of 2A produces a flux of 0.04 mWb in coil A while the same current in B creates in it flux of 0.05 mWb. If Number of turns are 1000 and 13..
Calculate the frequencyto which the generated voltage drops before the steam flowcommences toincrease to meet the new load. The value of the stored energy forthe machine is5kW-sec per KVA of generator energy. Also calculate the value of Hconstant ..
Shows a pneumatic circuit diagram used for air supply and exhaust in an automatic control system - shows a pneumatic circuit in which four actuators are controlled.
A passenger in a helicopter traveling upwards at 27 m/s accidentally drops a package out the window. If it takes 19 seconds to reach the ground, how high to the nearest meter was the helicopter when the package was dropped?
