Air flows through a pipe with a variable cross section. at the pipe inlet the pressure is 6.0 bars, the temperature is 27? ,the area is 35.0 cm, and the velocity is 60 m/s at the pipe exit the conditions are 5.0 bars and 50°c, and the cross-sectional area is 20.0 cm2. find a) the mass flow rate, in kg/s, and b) the exit velocityin m/s. (1.46 kg/s, 135.7 m/s)

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
