In a food-drying facility, a constant-diameter heated pipe is used to raise the temperature of air. At the pipe entrance, the velocity is 12 m/s, the pressure is 100 kPa absolute, and the temperature is 20°C. At the outlet, the pressure is 90 kPa absolute and the temperature is 80°C. What is the velocity at the outlet? Can the Bernoulli equation be used to relate the pressure and velocity changes? Explain.
