A concentric tube, i.e. tube-in-tube, heat exchanger uses water at 15 °C to cool ethylene glycol from 100 °C to 60 °C. The water and glycol flow rates are each 0.5 kg/s. The specific heat of glycol and water are 2637 J/kg-K and 4180 J/kg-K, respectively
What is the maximum possible heat transfer rate (kW)?
What is the outlet temperature of the water (°C)?
What is the effectiveness of the heat exchanger? = 0.470
Based on the fluid outlet temperatures can you discern whether the heat exchanger is a parallel or counter flow configuration? Explain
