Carbon dioxide flows in a horizontal duct at 7 bar abs. and 300 K with a velocity of 20m/s. At a dowstream section, the pressure is 3.5 bar abs and the temperature is 280 K. if 1.4 x 10^4 j/kg of heat is lost by the fluid between these locations..... 1) Determine the velocity at the second location. B) Compute the ratio of inital to fial area.
