1. A solid metal ball has diameter 2 cm (k = 42.6w/m°C, a = 0.043m²/h), initially temperature at 500°C. It is then placed in the middle of a stream of very fast flowing, cool liquid of temperature 45°Cand constant every time. Heat transfer to an environment with convective heat transfer coefficient 200 w/m²°C. The cooling process was unsteady state. a) How profile temperature in the ball as function t and r? b) Solution with separation method c) Solution with Laplace Transform
