Air at 2 atm and 200 C is heated as it flows through a tube with a diameter of 1 in (2.54 cm). What's the type of flow that necessary to received heat flux at constant rate (1291.44 w/m2 ) that maintained at the wall and the wall temperature is 20 c above the air temperature? Also, find the length of the tube to obtain an increase of air temperature by 40 C. Properties of air at 200 °C| Pr=0.681 u = 2.57 x 10 kg/m-s k = 0.0386 W/m-°C Cp =1.025 kJ/kg-°C
