Question:
Engine oil flows at a rate of 0.5 kg/s through a 2.5 cm ID tube. The oil enters 25?C while the tube wall is at 100?C.(a) If the tube is 4 m long. Determine whether the flow is fully developed.(b) Calculate the heat transfer coefficient.GIVENEngine oil flows through a tubeMass flow rate (m) = 0.5 kg/sInside diameter (D) = 2.5 cm = 0.025 mOil temperature at entrance (Ti) = 25?CTube surface temperature (Ts) = 100?CTube length (L) = 4 mASSUMPTIONSSteadystate
