4. A manufacturing engineer claims that a concentric tube heat exchanger with a heating surface area of 2 m2 could be used to cool the exhaust gases from 300° C to 20° C by using water entering the system at 10°C at the rate of 1500 kg/hr. If the gases flow through the heat exchanger at the rate of 1200 kg/h and the overall heat transfer coefficient is 500 kJ/m2 h °C, prove that his claim is correct. Cp of the exhaust gases is 1.12 kJ/kg °C

4. A manufacturing engineer claims that a concentric tube heat exchanger with a heating surface
area of 2 m2 could be used to cool the exhaust gases from 300° C to 20° C by using water
entering the system at 10°C at the rate of 1500 kg/hr. If the gases flow through the heat
exchanger at the rate of 1200 kg/h and the overall heat transfer coefficient is 500 kJ/m² h °C.
prove that his claim is correct.
Cpof the exhaust gases is 1.12 kJ/kg °C
