Air at (4.70x10^2) K flows out of a circular pipe at 101325 Pa as shown in Figure. The mass flowrate of the air at the pipe entrance is 0.0093 kg/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 Velocity if 2000 J of heat is added to the pipe. Answer should be in m/s with three significant figures.
