Question:

Water flows through a 2.5-cm-ID pipe 1.5 m long at a rate of 1.0 kg/s. The pressure drop is 7 kPa through the 1.5-m length. The pipe wall temperature is maintained at a constant temperature of 50oC by a condensing vapor, and the inlet water temperature is 20oC. Estimate the exit water temperature.
