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 Ti = 240 ° C. According to the heat transfer coefficient between the plate and oil h = 600 W / m2K and p = 7833 kg / m3 for steel, cp = 465 J / kgK, k = 43 W / mK, α = 1.2x10-5m2 / s (a) after how long the core temperature of the steel plate becomes 100 ° C (b) What is the temperature within 3 cm from the surface of the steel plate (c) What will be the amount of heat transferred to the unit length plate during this time?
