Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

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.
Answer should be in 'K' with three significant figures.
Note: Your answer is assumed to be reduced to the highest power possible.
