Explanation:
The frequency of an organ pipe if it is open is given by :
v is speed of sound in air is 343 m/s at 20°C
For fundamental frequency, n = 1
First overtone frequency,
Second overtone frequency,
Third overtone frequency
Hence, this is the required solution.
The velocity at the end of vaneless space(state 3) is 965.92 m/s
<h3>What is centrifugal compressor?</h3>
It increases kinetic energy to the airstream using a rotating element and then converts it into potential energy in the form of pressure.
Temperature at state 2, T₂ =T₀ + c/2Cp
Substitute T₀ =450K, c=250m/s, Cp =1005, we get
T₂ =418.90K
From the velocity triangle, sinβ₂ =c₂/v₂
v₂ = 250/sin (90°-75°) = 965.92 m/s
Thus, the velocity at the end of vaneless space is 965.92 m/s.

Answer:
Your weight is the combination of all the large-scale, long-term forces on your body. While the earth's gravity is by far the strongest large-scale force, it is not the only one. What you experience as "something pulling you down" is actually the total of all the forces and not just gravity. The four dominant large-scale,
Explanation:
Answer:
Explanation:
As we know that when runner is moving on straight track then the net force on his feet is given as
while when runner is moving on circular track then we have
now percentage change is given as
First, calculate for the distance between the given points A and B by using the equation,
<span> D = sqrt ((x2 – x1)2 + (y2 – y1)2)</span>
Substitute the known values:
<span> D = sqrt((9 – 2)2 + (25 – 1)2)</span>
<span> D = 25 m</span>
I assume the unknown here is the time it would require for the particle to move from point A to B. This can be answered by dividing the calculated distance by the speed given above.
<span> t = (25 m)/ (50 m/s) = 0.5 s</span>
<span>Thus, it will take 0.5s for the particle to complete the route. </span>
