THANK YOU In Rizal province, one of its power plants has been thoroughly monitored for possible conversion into a wind power plant. A propeller wind turbine is to be used. Survey showed that Rizal Province at a height of 10 meters above the ground has a minimum wind speed of 7.1 miles per hour duringthe month of June and a maximum wind speed of 12.9 miles per hour during the month of January. The minimum temperature is at 75 degree Fahrenheit during the month of January and maximum temperature is at 89 degree Fahrenheit during the month of May. The existing power plant has an output of 54MW. For the proposed wind power, the power coefficient of turbine is 35% and the generator efficiency is 95%.

The pilot knew the wind vector (30 m/s, 220 degrees), and was paid to go to a destination at 140 degrees. The pilot wrote the destination vector as (unknown resultant speed, 140 degree) and the plane vector as (45 m/s, unknown flying angle). Use vector drawing to find the unknown resultant speed and unknown flying angle. Show a vector diagram with scale. Hints Draw the wind vector first, then use the end-tip of the wind vector to draw the destination vector as a line at 140 degrees, then use the start-tip of wind vector to draw a circle with radius 45 m/s. Use the intersection of the 45 m/s radius circle and the 140 degrees line to complete the vector triangle.arrow_forward
