Please consider a 50 x 100 x 300 mm long duct channel. Air flows through the duct with V= 5 m/s and T= 25 C. A stainless steel cylindrical heating element is located in the middle of the duct. Temperature and radius of the heating element are T= 400 C and R= 17 mm, respectively. According to these conditions, please calculate outlet temperature of the air flow and average "wall heat transfer coefficient" of the cylindrical heating element 50.00 100.00 300.00
