Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window

Steam enters a converging nozzle at 3.0 mpa and 500°c with a negligible velocity, and it exits at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: is isentropic (a) (b) has an efficiency of 94 percent

Air flows over a flat plate at a velocity of 3 m/sec and ambient conditions are, the pressure is 761 mm of hg and tempera- ture is 15°c. the plate is maintained at 85°c. if the length of the plate is 100 cm along the flow of the air, find out the heat lost by 50 cm of the plate which is measured from the trailing edge. plate width is 50 cm.
