Question: Problem 3 : A counterflow heat exchanger uses 6 5 0 0 k g h of water ( c p = 4 . 1 8

Problem 3: A counterflow heat exchanger uses 6500kgh of water (cp=4.18kJkgK) entering at 298 K to cool 13,000kgh of oil (cp=2.09kJkgK) entering at 373 K . The total surface area of the heat exchanger is 16m2, and the overall heat transfer coefficient is 350Wm2K. Find the outlet temperatures of the two fluids using both the LMTD method and the -NTU method.
