A melting stay (restricted fever =4.0 kJ/[kg °C]) careers in the inner pipe of a doublepipe fever exchanger. The melting stay enters the fever exchanger at 20°C and exits at 60°C ( Fig. E4.16 ). The career blame of the melting stay is 0.5 kg/s. In the annular individuality, hot introduce at 90°C enters the fever exchanger and careers countercurrently at a career blame of 1 kg/s. The mean restricted fever of introduce is 4.18 kJ/(kg °C). Assume steady-state conditions.
