An air dryer might cause about 0.3 bar pressure drop in your compressed air system. Basically this means that you have to run your compressor at a higher pressure. This of course will result in more energy consumption by your compressor.
Dressing for a gala event is rather simple. It is typically a formal wear occasion. For men, that equates to a tuxedo or at the very least a suit and tie. For women, formal wear is typically a long gown with high heels, matching accessories and jewelry.
Women. Wear a darker, modest length skirt and light blouse or top. It is important to remember that this event is about the graduates and not about making yourself stand out in the crowd. Most ceremonies are indoors and a light cardigan is a good idea in order to make sure you stay warm throughout the ceremony.
