11-172 A single-pass crossflow heat exchanger with both fluids unmixed has water entering at 16°C and exiting at 33°C while oil (c=1.93 kJ/kg-K and p = 870 kg/m³) flowing at 0.19 m/min enters at 38°C and exits at 29°C. 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.
