  2. An infinitely long furnace of 0.5 m 0.4 m cross-section is shown in the figure below Consider all surfaces of the furnace to be black. The top and bottom walls are maintained at temperature T1 = T3 = 927 C whil walls The view factor, F1-2 is 0.26. The net radiation heat loss or gain on side 1 is Stefan-Boltzmann constant - 5.67 x 10-8 W/m2-K4 W/m. Side 3, T Side 4, T Side 2, T0.4 m emperature T): Side , T 4= 527 C. 0.5 m

  7. Using the Clausius- Clapeyron equation, an estimate of the enthalpy of evaporation of water at 25 C (in kJ/kg) is For water at 250C, dp./dTs 0.189kPa/K (ps is the saturation pressure in kPa and T. is the saturation temperature in K) and the specific volume of dry saturated vapour is 43.38 m3/kg. Assume that the specif negligible in comparison with that of vapour. me of liquid is
