There are two conditioned spaces (24°C) from the other two sides. The outside temperature is 40°C, floor temperature is 18°C, and the room inside freezing temperature is -18°C. For the product, the mass flow rate is 1000 kg/h, Cp=1.5 kJ/(kg.K), inlet temperature is 15°C, water content is 25%, and the freezing point is -3°C.

A radiant-heating system is installed in the plaster ceiling of a room 36 ft long by 18 ft wide by 9 ft high. Assume direct radiation. The temperature of the concrete floor is maintained at 75°F. The temperature of the air passing through the room is held at 75°F. If the required heat supply to the floor is 8000 BTU/hr, calculate the necessary temperature at the ceiling surface. How much heat is transferred to the air, in BUT/hr? Emissivity of plaster = 0.93; absorptivity of concrete = 0.63. The convective heat-transfer coefficient between the ceiling and the air is given by the equation hc = 0.20 (AT)¹/4.
The operators have noticed that the performance of the reactor is somewhat different to thedesign specifications and suspect that the thermal cycling may be responsible. The seniorprocess engineer would like you to analyse two periods:- The period when the reactor is initially heated up and held at the operating temperature.- The period after the reactor is taken offline for maintenance and then heated up again.You should consider the effect of the tube expansion on the operating variables and theoverall effect on pressure drop and conversion. Compare these responses to the estimatedperformance according to the design basis.You may include any equations or diagrams that you consider necessary to support yourdiscussion. A numerical solution is not required.Hints: A general consideration of the design method for fixed bed reactors may revealrelationships between operating and performance variables.
