Assignment Help Mechanical Engineering
Reference no: EM13965394

A large steel plate 5 cm thick is initially at a uniform temperature of 400oC. It is suddenly exposed on both sides to a surrounding at 60oC with convective heat transfer co-efficient of 285 W/m2K.

Calculate the centre line temperature and the temperature inside the plate 1.25 cm from themed plane after 3 minutes.

Take K for steel = 42.5 W/mK, ? for steel = 0.043 m2/hr.
