Homework: A counterflow heat exchanger is located between a collector and a storage tank. The fluid in the collector side is a water-glycol mixture with cp=3840 J/kg. °C and a flow rate of 1.35 kg/s, whereas the fluid in the tank side is water with a flow rate of 0.95 kg/s. If the UA of the heat exchanger is 5650 W/°C, the hot glycol enters the heat exchanger at 59°C, and the water from the tank at 39°C, a) estimate the heat exchange rate; b) if FRUL is 5.71 W/m².°C and collector area is 16 m², what is the ratio FR/FR?

Question
Transcribed Image Text:Homework: A counterflow heat exchanger is located between a collector and a storage tank.
The fluid in the collector side is a water-glycol mixture with cp=3840 J/kg. °C and a flow rate
of 1.35 kg/s, whereas the fluid in the tank side is water with a flow rate of 0.95 kg/s. If the UA
of the heat exchanger is 5650 W/°C, the hot glycol enters the heat exchanger at 59°C, and the
water from the tank at 39°C, a) estimate the heat exchange rate; b) if FRUL is 5.71 W/m².°C
and collector area is 16 m², what is the ratio FR/FR?
