Consider two identical generating units with equal (4 %) speed-droop that operate in parallel

in accordance with the frequency-load characteristics as shown below.

(a) If both units are set to operate on curve A and the total load is equal to 100 % of the rating

of one unit, what percentage of rated kW output is each unit supplying and what is the

frequency of the common busbar?

(b) Repeat (a) if the total load is equal to 200 % of the rating of one unit.

(c) If one unit is set to operate on curve B (while the other remains operating on curve A) and

the total load is equal to 100 % of the rating of one unit, what percentage of rated kW

output is each unit supplying and what is the frequency of the common busbar?

(d) Repeat (c) if the total load is equal to 150 % of the rating of one unit? How would you

characterize operation with any further increase in total load?.

A 106-102 100

B 104-100 100

Consider two identical uniform bricks each of length "L" which are staggered and stacked in parallel with one on top of the other. Find the maximum possible overhang beyond the table's edge the system can have without toppling. Express your answer in terms of "L." Hint: apply the "free-standing body" theorem THREE TIMES.

Two identical firms (identical cost functions) operate on a market. For each of the following market demand curves and cost curves determine the Bertrand, Cournot, and Stackelberg outcomes (prices, quantities, and profits - for each firm, and at the market level). Also determine the collusive outcome (assuming the two firms form a cartel). Compare the outcomes. a) P = 200 − 2Q, T C = 50 + 10Q (PB = 10, PC = 73.33, PS = 57.5, PM = 105)...

Two parallel conducting plates have equal and opposite charges. Consider the area of conducting place is 2.5 cm^2 and the capacitor is filled with 1.8 m thick dielectric material which has K=3.60 dielectric constant. The resultant electric field in the dielectric is 1.20×106 V/m. a-Find the magnitude of the charge density σ on the conducting plate. b-Calculate the magnitude of the charge density σ1 on the surfaces of the dielectric. c-Determine the total electric-field energy U stored in the capacitor.

Two identical plate capacitors each with the capacity C = 0.01μF are connected in parallel. The capacitors were charged to a voltage of U = 300 V and disconnected from the voltage source. The plates of one of the two capacitors were then pushed apart to a distance twice the original plate distance. What charge flows through the wires?

Two identical capacitors each consists of two circular parallel plates with a radius of 1.6 cm and a separation distance of 3.0 mm. They are filled with a dielectric which has a dielectric constant (strength) of LaTeX: \kappaκκ = 32. These two capacitors are connected in parallel, and connected to a 1.5V battery a) what is their total capacitance? b) If the dielectric is removed what is the total capacitance? c) What energy is stored on the capacitors when they...

Two identical balls are launched with the same initial speed, but at different angles with respect to the horizontal. They both land at the level they were launched from, and they have the same range (they travel the same horizontal distance). The maximum height reached by one ball is exactly twice as high as the maximum height reached by the other ball. The two launch angles are closest to which of these pairs? (the answer is 55 and 35). Can...

A student placed equal volumes of honey and of water in two, identical, open dishes, and left them at room temperature for 8 hours. She observed that the amount of water decreased, but the amount of honey seemed unchanged. Knowing that honey is a highly concentrated solution of sugar in water, which statement should the student make to explain this phenomenon? Honey has a much lower vapor pressure than pure water has. So, pure water evaporates at a much higher...

Two identical capacitors are connected in parallel, and each acquires a charge Q0 = 1.12E-6 C when connected to a source of voltage V0 = 2.45 V. The voltage source is disconnected, and a dielectric with constant ? = 2.00 is inserted to fill the space between the plates of one of the capacitors. What is the smaller of the two final capacitor charges? What is the larger of the two final charges? What is the final volatge across the...
