Air enters a compressor operating at steady state with a pressure of 14.7 lbf/in.2 , a temperature of 80of, and a volumetric flow rate of 1000 ft3 /min. at the exit, the pressure is 100 lbf/in.2 and the temperature is 400of. using the ideal gas model, determine the diameter of the exit duct so the exit air velocity does not exceed 700 ft/s.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
