A 10 cm thick and 1 m wide long steel plate is immersed in an oil bath at T0=40°C when the temperature is T1=240 ° C. Heat transfer coefficient between plate and oil is h=600 W/m2K and p=7833 kg/m3 for steel, cp=465 J/kgK, k=43 W/mK, (alpha) = 1.2x10^(-5) m2/s. A) After how long the core temperature of the steel plate becomes 100 ° C. B) What is the temperature inside 3 cm from the surface of the steel plate happens. C) Within this period, per unit length plate what is the amount of heat that passes.
