Hot waters enters a radiator at a rate of 0.5 kg/s, losing heat from 100°C to 75°C. Air flows across the radiator through the interfin spaces and is heated from 23°C to 38°C. The radiator is a compact cross-flow water-to-air heat exchanger with both fluids (air and water) unmixed, having 50 tubes of internal diameter 5 mm and length of 60 cm. Determine the overall heat transfer coefficient of this radiator based on the inner surface area of the tubes.
