Answer:
Power generated = 4.315 kW
Step-by-step explanation:
Given,
- speed of wind when enters into the turbine, V = 12 m/s
- speed of wind when exits from the turbine, U = 9 m/s
- mass flow rate of the wind, m = 137 kg/s
According to the law of conservation of energy
Energy generated = change in kinetic energy
Since, the air is exiting at same elevation. So, we will consider only kinetic energy.
Energy generated in one second will be given by,


=4315.5 J
= 4.315 kJ
So, energy is generated in one second = 4.315 kJ
Power generated can be given by,

And the energy is generated is already in per second so power generated will be 4.315 kW.
2/10, but reduced would be 1/5.
10 / 2 - 5
2 / 2 - 1

Answer: 5F < 5( X + x )
Step-by-step explanation:
Let each finger = F and
The index finger = X
The shortest index finger = x
the combined length of all 5 of her fingers on one hand should be less than 5 times the length of index finger
From the statement above, we get
5F < 5X
Tessa add the second shortest index finger.
That is
5F < 5( X +x)
