This is all shown on the web at http://www.dream-models.com/eco/vacuumpump.html. It is a simple step by step guide of just what you want.
Found using simple web search! Who ever teaches you computer studies or information technology should be hanging their head in shame that they haven't taught you how to do these basic seaches!
It also depends how effective a vacuum you need to achieve.. any air pump will lower the pressure.
Look at the site for calculation guidance
