Asmall cubical furnace x by x by x cm on the inside is constructed of fireclay brick [k=1.04 w/m·°c] with a wall thickness of 10 cm. the inside of the furnace is maintained at 500°c, and the outside is maintained at 50°c. (a) calculate the side length x of the cubical furnace, if the heat lost through the walls is 8250 kw. (b) plot the graph q-x, i. e. heat lost vs. side length of furnace (c) for what value of x will the heat lost through the walls be equal to 16500 kw? (d) assume that x=50cm. plot the graph q - t, where q is the heat lost through the walls and t is the wall thickness.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2

Air (c-1.006 kj/kg. k, r-0.287 kj/kg. k) enters a nozzle steadily at 280 kpa and 77°c with a velocity of 50 m/s and exits at 85 kpa and 320 m/s. the heat losses from the nozzle to the surrounding medium at 20°c are estimated to be 3.2 kj/kg. determine (a) the exit temperature and (b) the total entropy change for this process. solve this problem using constant specific heats.
