A single-pass cross-flow heat exchanger with both fluids unmixed has water entering at 16C and exiting at 33C, while oil (Cp = 1.93 kJ/kg-K; ρ = 870 kg/m3) flowing at 0.19 m3/min enters at 38C and exits at 29C. If the surface area of the heat exchanger is 20 m2, determine a) the NTU value and b) the value of the overall heat transfer coefficient.
