Often, ...the surgeon expects a lower room temperature than that stated in guidelines. for a 450 ftÂ² (42 mÂ²) surgery room with a 10 ft (3 m) ceiling height, 15 ACH equates to 1,125 cfm (531 L/s) of supply air.ensible heat added by the adsorption process raises the supply-air dry-bulb temperature to 55Â°F (13Â°C). Mixed air (MA) entering the regeneration side of the wheel is at a lower relative humidity (about 50%).
Smocking may be done in many sophisticated patterns. A. Cable stitch: a tight stitch of double rows that joins alternating columns of gathers. B. Stem stitch: a tight stitch with minimum flexibility that joins two columns of gathers at a time in single overlapping rows with a downward slope.
Tips. 1  The amount of fabric you use for smocking is bigger than the amount you need to make an unsmocked item for a child. 2  The fabric's thickness affects how many pleats per inch you place. 3  If you use a pleather, place your smocking dots farther apart, both horizontally and vertically.
