Chapter 1, Problem 1.2E
To determine

The reason for the operating room pressure in hospitals is a positive pressure relative to adjacent spaces.

Expert Solution & Answer

Answer to Problem 1.2E

The pressure in the operating room is more than the adjacent space because the surrounding air cannot enter the room.

Explanation of Solution

In positive pressure rooms, the treated region is kept at a higher pressure than the surrounding air. This indicates that air can enter the space but not return. Any airborne particle from the room will be filtered out in this way. This is safe for the patient.

The positive pressure means the operating room pressure is higher than the adjacent spaces and negative pressure means the operating room pressure is lower than the adjacent spaces. The operating room is maintained at positive pressure because it prevents the outside air to enter the room.

A negative pressure chamber, on the other hand, uses decreased air pressure to let outside air enter the isolated environment. Preventing internal air from exiting the room, captures and maintains potentially dangerous particles there. In medical facilities, negative pressure rooms separate patients with infectious diseases and shield others outside the room from exposure.

Conclusion:

Thus, the positive pressure means the operating room pressure is higher than the adjacent spaces.

A particular furnace is shaped like a section of a cone. The top surface of the furnace is uniformly heated by a resistance heater. During operation, the top surface is measured to be 800 K and the power supplied to the resistance heater is 1750 W/m². The sidewall of the furnace is perfectly insulated with ε = 0.2. If the emissivity of the top and bottom surfaces are ε = 0.5 and > = 0.7, respectively, determine the temperatures of the sidewall and the bottom surface of the furnace.

You are designing an industrial furnace to keep pieces of sheet metal at a fixed temperature. You decide a long, hemispherical furnace will be the best choice. The hemispherical portion is built from insulating brick to reflect the radiation from a ceramic plate onto the sheet metal and the ceramic plate is heated by gas burners from below. An insulating wall prevents direct transmission of radiative energy from the ceramic plate to the sheet metal. The radius of the hemisphere is 1 m and the rest of the system properties can be found in the table below. You may neglect convection during your analysis.
