Mixing Methods

Question 2. 10 points If the zero sequence currents flowing from a generator with a grounded neutral are all equal to 1 + j0 per unit, find the neutral current. 

The harder the wheat kernel, the higher its protein content.

Fermenting and proofing both refer to the dough rising.

As its name implies, all-purpose flour can be substituted in any recipe that calls for cake or bread flour.  

Question 5. 15 Points The fuel-cost functions in $/h for two thermal generation stations are given by C1 = 800 + 6.0P1 + 0.004 P12 C2 = 1000 + 6.8P2 + 0.002 P22 where P1 and P2 are in MW. The total power demand is 1300 MW. Neglecting losses, determine the optimal generation of each plant and the incremental cost of power λ ($/MWh).

Air is one leavening agent that is present in all baked goods.

Question 4. 25 Points A single area consists of two generating units, rated at 400 and 800 MVA, with speed regulation of 4 percent and 5 percent on their respective ratings. The units are operating in parallel, sharing 700 MW. Unit 1 supplies 200 MW and unit 2 supplies 500 MW at 1.0 per unit (60 Hz) frequency. The load is increased by 130 MW. Assume there is no frequency-dependent load, i.e., D = 0. Find the steady-state frequency deviation and the new generation on each unit.

Match the mixing technique with the appropriate fat used for the method. 

Once a system becomes stable, maintenance costs usually remain low and involve minor _____ maintenance.​
