A power station has a daily load cycle as under :
260 MW for 6 hours ; 200 MW for 8 hours : 160 MW for 4 hours, 100 MW for 6 hours.
If the power station is equipped with 4 sets of 75 MW each, calculate
(i) daily load factor
(ii) plant capacity factor and
(iii) daily requirement if the calorific value of oil used were 10,000 kcal/kg and the average heat rate of station were 2860 kcal/kWh.
By the method of approximation, using familiar geometric shapes, find the area under the curve of given figure from zero to 10 s.
This counter has an output"odd" whose value is 1 when the current count value isodd. Use the sequential design technique. Start from a state diagram, draw the state table, minimize the logic, and draw the final circuit.
What is the new angular speed when the man walks to a point 1.7 m from the center?
If a potential V0 is given on the positive x axis, calculate the potential everywhere in the first quadrant. Hint: Use cylindrical coordinates.
A student project is required to be portable and hand held. It requires 6 V DC power at a current of 150 mA. The batteries for the power supply must last for a minimum of 7 hours of continuous operation.
explain why the circuit does not operate as a rectifier.
A sinusoidal signal is riding on a 2 v DC offset (in other words, the average value of the total signal is 2 v). Design a circuit to remove the DC offset and amplify the sinusoidal signal (without phase reversal) by a factor of 100.
A 100-hp 440-V 0.8-PF-leading Δ-connected synchronous motor has an armature resistance of 0.22Ω and a synchronous reactance of 3.0Ω. Its efficiency at full load is 89 percent. What is the input power to the motor at rated conditions?
Add Z1 = 3ej30 degree and Z2 = 4e -j60 degree together. Write your result in both rectangular and polar form. In polar form, indicate whether your angle is in radians or degree s. Multiply Z1 = -2 + j3 and Z2 = 4 + j2 together.
An analog signal xa(t) is bandlimited to the range 900 = F = 1100 Hz. It is used as an input to the system shown in figure. In this system, H(?) is an ideal lowpass filter with cutoff frequency Fc = 125Hz. (a) Determine and sketch the spectra for ..
State the main reasons for the use of excitation control using feedback of terminal voltage for a turbo generator supplying powerto a complex power system.
Counteris normally stopped, when a momentary switched is pressed thecounter would count. When switch is released counter wouldstop. Realizing that not all random generated numbers would work a Forbidden Combination Detector has to be implemented t..
