Aplane wall of thickness 0.1 m and thermal conductivity 25 w/m·k having uniform volumetric heat generation of 0.3 mw/m3 is insulated on one side, while the other side is exposed to a fluid at 32°c. the convection heat transfer coefficient between the wall and the fluid is 500 w/m2·k. determine the maximum temperature in the wall.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
