Assignment Help Mechanical Engineering
Reference no: EM132641283

A slab of aluminum 5cm thick initially at 200 deg C is suddenly immersed in a liquid at 70 deg C for which the convective heat transfer coefficient is 525 W/m2K. Determine the temperature at the depth of 12.5mm from one of the faces 1 min after immersion.

Also calculate the energy removed per unit area from the plate during 1 min of immersion. Take density= 2700Kg/m3, c= 09 Kj/KgK, k= 215 W/mK, alpha = 8.4x 10-5 m2/s.
