A base load station having a capacity of 18 MW and a standby station having a capacity of 20MW share a common load. Find the annual load factors and plant capacity factors of two power station from the following data :
•Annual standby station output = 7.35 x 106 kWh•Annual base load station output = 101.35 x 106 kWh•Peak load on standby station = 12 MW•Hours of use by standby station/year = 2190 hours
An abc-phase-sequence three phase voltage source connected in abalanced wye supplies power to a balanced delta-connected load. Theload current Iab = 4
Several type 741 op-amps, some switching diodes,and +5 V and -5 V power supplies are also available. Draw acircuit diagram showing how an inverting amplifier with a gain of -1.5 can beconstructed with these components only.
An ice chest at a beach party contains 12 cans of soda at 2.36 °C. Each can of soda has a mass of 0.35 kg and a specific heat capacity of 3800 J/(kg C°). Someone adds a 8.06-kg watermelon at 26.3 °C to the chest.
Calculate the earth loop impedance, minimum fault current (neglect the supply/earth impedance) and select an appropriate fuse for the circuit with reference.
An inventor claims to have perfected an engine that wil produce power from energy transferred as heat from a 1000K flame. Energy wil be rejected as heat to the ground at 290 K. A 75 percent energy conversion efficiency is claimed.
A parallel RC circuit is connected to a 100-volt 60 Hz source. The current flow through the resistor is measured and found to be 10amps. The current flow through the capacitor is measured and foundto be 10 amps.
In problem 1 and 2, find a system of differential equations and initial conditions for the currents in the networks given by the schematic diagrams: the initial currents are all assumed to be zero. Solve for the currents in each branch of the netw..
DESIGN A mod 6 counter that counts in the natural sequence. DO NOT include the undesired states in your design (therefore, you will have don't care condition ). show all steps for the complete design of this synchronous counter
Design a serial 2's complementer with a shift register and aflip-flop. the binary number is shifted out from one side and its2's complement shifted into the other side of the shift register.
Create a function that transmits one byte to an HD44780 LCD controller using the following sequence. Allow one microsecond between each instruction. To clock in a byte: Set the E line low.
The preceding example demonstrated the required amplitude response of the VSB filter. We now consider the phase response.
If the slip is 5%, determine (a) the rotor copper loss, (b) the total mechanical power developed by the rotor, (c) the output power of the motor if friction and windage losses are 750 W, and (d) the efficiency of the motor, neglecting rotor iron l..
