Systems engineers began as a field for which reason? To aid with large-scaled defense systems in the 1950s.

To facilitate space travel in the 1960s.

To discover new sources of fuel in the 1970s.

To respond to the growth of computer technology in the 1980s.

The inner surface of a 0.25m thick brick wall of a furnace is kept at 810ºc, when the outside surrounding air is at 22ºc. the convective heat transfer coefficient of the outer surface is 12 w/m2k and the thermal conductivity of the brick is 0.865 w/mk.neglect the convective resistance for the inner side of the furnace and assume that the problem is steady state and thermal radiation is neglected. (a)-sketch the system and calculate the rate of heat loss per unit wall area. (b)-calculate the temperature of the outer wall surface.
