Carbon dioxide (co2) at 1 bar, 300 k enters a compressor operating at steady state and is compressed adiabatically to an exit state of 10 bar, 530 k. the co2 is modeled as an ideal gas, and kinetic and potential energy effects are negligible.
for the compressor, determine:
(a) the work input, in kj per kg of co2 flowing,
(b) the rate of entropy production, in kj/k per kg of co2 flowing, and
(c) the percent isentropic compressor efficiency.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

im pretty sure its

(8,15)

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
