Then there is pressure measurement. kilogram squared. Fer instance: 40 lbs or so of oil pressure is a little over 5 kg/sq. This is not an exact figure but close enough. 73, Gary... wa6fgi -- Original
OK, as a physicist I feel compelled to jump into this a little bit. Pressure is in units of force per unit area. "40 lbs" of oil pressure commonly means "40 pounds [a force] per square inch [an area]
But George, it was you who showed us how to measure air flow the easy way... in units of seconds per garbage bag. -- 73 from Ian G/GM3SEK _______________________________________________ Amps mailing
