QUESTION 3: In an underbody tube pass heat exchanger, With the machine oil flowing on the body side, 10.000 kg / h flow rate water is heated from 15 oC to 85 oC. Oil, counter flow enters the heat exchanger at a temperature of 150 oC, at a temperature of 95 oC comes out. Average heat transfer coefficient on the oil side 350 W / m2K. Water with inner and outer diameters of 22.9 mm / 25.4 mm 10 Iron (k = 40 W/ mK) flows through the pipe. a) Calculate the heat transfer coefficient (W / m2K) on the water side b) Calculate the total heat transfer coefficient (W / m2K) c) Calculate the total heat transfer area (m2 )

pass heat exchanger,
With the machine oil flowing on the
body side, 10.000 kg / h flow rate
water is heated from 15 oC to 85 oC.
Oil, counter flow
enters the heat exchanger at a
temperature of 150 oC, at a
temperature of 95 oC
comes out. Average heat transfer
coefficient on the oil side 350
W / m2K. Water with inner and outer
diameters of 22.9 mm / 25.4 mm 10
Iron (k = 40 W/ mK) flows through the
pipe.
a) Calculate the heat transfer
coefficient (W / m2K) on the water side
b) Calculate the total heat transfer
coefficient (W / m2K)
c) Calculate the total heat transfer area
