Manometer frequency range

  1. Jul 5, 2013 #1
    Is manometer suppose to work below its natural frequency ?
    I saw a textbook problem asking to design a manometer with its natural frequency way way below the pressure's fluctuation frequency, so was confused.

    Think about how a traditional manometer works physically. When temperature varies slowly, the manometer keeps up just fine. What happens if the temperature varies very quickly?

    Also, how do you think you would calculate the "natural frequency" of a manometer? Think resonance...
