Check out this calculator. This is basically your predicted normal peak flow or peak expiratory flow rate(PEFR).
This is the normal for a person of your age and height. However, it may not be YOUR normal. The best way to determine your normal peak flow -- better known as your PERSONAL BEST PEAK FLOW -- is to blow in your peak flow meter every morning and every evening. Whatever is the highest peak flow you blew is considered your Personal best. That is what you use to monitor your asthma.
For more information on peak flows, check out this post I wrote a few months back.
