Air enters the compressor of a gas-turbine plant at ambient conditions of 100 kpa and 25°c with a low velocity and exits at 1 mpa and 347°c with a velocity of 90 m/s. the compressor is cooled at a rate of 1500 kj/min, and the power input to the compressor is 260 kw. determine the mass flow rate of air through the compressor. (round the final answer to the nearest three decimal places.)

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
