Question
Consider a counter-flow heat exchanger with the inlet temperatures of two fluids (1 and 2) being K and K. The heat capacity rates of the two fluids are W/K and W/K, and the effectiveness of the heat exchanger is 0.5. The actual heat transfer rate is _____ kW.(Answer in integer)
Correct answer
9.999 to 10.001
Solution
The maximum possible heat transfer rate () is given by:Where:
- W/K
- K (hot fluid inlet)
- K (cold fluid inlet)
