An engine running at a temperature of 25°C is fueled by a constant 0.05 l/s gas flow via a pipe with a diameter of 3.0 cm. At 25°C the gas has a viscosity of 0.85 mPa · s. If the engine runs in a hotter environment, its temperature increases to 55 °C. Determine Reynolds number and the type of gas flow through the pipe at 55 °C, knowing that the gas density is 1,100 kg/m3 at all temperatures and the coefficient of linear expansion for the pipe is α = 550 × 10-6 K-1.
