Problem 08.119-Liquid hydrocarbon temperature A liquid hydrocarbon enters a 3.9-cm-diameter tube that is 5.0 m long. The liquid inlet temperature is 20°C and the tube wall temperature is 60°C. Average liquid properties are cp=2.0 kJ/kg-K, μ-10 mPa-s, and p = 900 kg/m³. At a flow rate of 1200 kg/h, the liquid outlet temperature is measured to be 30°C. Estimate the liquid outlet temperature when the flow rate is reduced to 400 kg/h. The estimated liquid outlet temperature is [ "C.
