Asingle stage axial compressor has a rotor velocity, u = 314 m/s, at the mean radius of 1 meter. the axial flow velocity remains constant through the stage at a value of 100 m/s. 1 = 0 degrees and 2 = 30 degrees. cp = 1 kj/kgk,  = 1.4 and r= 287 j/kgk. a) draw the velocity triangles (superimposed on each other) for the inlet and outlet of the rotor. b) what are 1 and the magnitudes of c1 and w1? c) what is c?

where’s the list ? the question is incomplete

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
