Question
![A double-pipe parallel-flow heat exchanger is to heat water (cp=4180 J/kg*K) from 25°C to
80°C at a rate of 0.5 kg/s. The heating is to be accomplished by geothermal water (cp = 4310
J/kg*K) available at 160°C at a mass flow rate of 0.75 kg/s. The inner tube is thin-walled and
has a diameter of 1 cm. If the overall heat transfer coefficient of the heat exchanger is 550
W/m²*K, determine the length of the tube required to achieve the desired heating.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6a2e60b5-531b-408d-ad87-91178dbcae31%2F97139722-40f8-4b47-8c68-63e1b593643a%2Fygto0bl_processed.png&w=3840&q=75)
