 The most important piece of advice I can give is have someone assigned to pay attention to the batteries. You cannot imagine how many teams end up saying "I thought you were charging the batteries..." - RoboMom [more] |

Re: Pressure physics problems
Sanddrag,
Read the problem carefully and see what they are asking for. Pressure is generally reported two ways: 1) absolute pressure (i.e. add in atmospheric pressure); or 2) relative pressure (i.e. how much pressure above atmospheric). Some problems require absolute pressure and some require relative. For example, tire pressure is relative pressure. Measuring pressure altitude with an altimeter is absolute pressure.

Re: Pressure physics problems
BY the way, relative pressure is often refered to as "guage" pressure. It is often indicated in the unit notation by adding a "g" at the end. Psi and psig are not the same thing.
