The steady-state temperature distribution in a one-dimensional wall of thermal conductivity 50 w/m k and thickness 50 mm is observed to be t(°c)=a+bx2, where a 200°c, b=-2000°c/m^2, and x is in meters. (a) what is the heat generation rate q in the wall? (b) determine the heat fluxes at the two wall faces. in what manner are these heat fluxes related to the heat generation rate

Determine the damped natural frequencies and the steady state response of a decoupled damped forced two degrees of freedom system. 10ä1 + 2q1 20q1 10 cos t; 10q2 +4q2 + 40q2 10 cos t

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
