An unfinned single-pass cross-flow heat exchanger is being designed with an available surface area of 0.471 m². The hot fluid (specific heat of 3120 J/kg-K) flows through the tubes with a mass flow rate of 0.4 kg/s. The cold fluid (specific heat of 4100 J/kg-K) has a mass flow rate of 0.2 kg/s. The overall heat transfer coefficient of the heat exchanger is 1100 W/m².K. Find the effectiveness of the heat exchanger. Assume thin copper tubes are used and neglect radiation. 0:404

Question
An unfinned single-pass cross-flow heat exchanger is being designed with an available surface area of 0.471 m².
The hot fluid (specific heat of 3120 J/kg-K) flows through the tubes with a mass flow rate of 0.4 kg/s. The cold
fluid (specific heat of 4100 J/kg-K) has a mass flow rate of 0.2 kg/s. The overall heat transfer coefficient of the
heat exchanger is 1100 W/m².K. Find the effectiveness of the heat exchanger. Assume thin copper tubes are used
and neglect radiation.
