Q=2000J Tout=? V(m/s) D=0.1m air Air at (3.15x10^2) K is entering in a circular pipe at 101325 Pa as shown in Figure. The velocity of the air at the pipe entrance is (1.0000x10^0) m/s. The diameter of the pipe is 0.1m. Specific gas constant of air is 287 J/kg-K. Specific heat of air is 1000 J/kg-K. Find the outlet temperature if 2000 J of heat is added to the pipe.

Just tell me if the angles are correct please !!!

Answer true or false in response to the following questions: (a) A force has zero moment about any point along its line of action. (b) A force has no moment about a line parallel to its line of action. (c) The magnitude of the moment of a force about a line equals the product of the component of the force perpendicular to the line and the distance between this component and the line. (d) The moment about a point P of the sum of a set of concurrent forces, placed at the point of concurrency (point P), equals the sum of the moments about P of the separate forces. (e) A couple has the same moment about any point. (f) If we know the moment of a couple about a point A, then we can find the moment of the couple about a specified line BC even if A does not lie on BC. (g) Two force and couple systems are equipollent if they have either the same resul- tant force or if the moments about some point P are the same for both systems. (h) It is possible for a system consisting of a single couple to…

If lengths a=5.9 m, b=2.3 m, c=3.4, and d=2.1, determine the angle (in degree) between the forces FB and FC. your answer must include 1 place after the decimal point.

*2–28. Resolve F, and F, into their x and y components. 60° 30° F = 400 N 456 F = 250 N

1: Determine the magnitude of F, and length y if F;=1500 N and x =1.75 m. You may assume that the tension in a rope on one side of a pulley is equal to the tension in the rope on the other side of the pulley. In making this assumption, you are neglecting the effects of friction. 2m
