Analisi del funzionamento di un orologio ad acqua
In this paper the author presents a discussion of the characteristics of a simple water clock built with a tin. Starting from experimental measurements, the emptying of the tin is theoretically described as a simple exercise. The theoretical result is tested on the experimental data and then used as model for the discussion. Finally the model is used to appraise the uncertainty in the measurement of time intervals and the clock?s inherent systematic errors. It is concluded that, if correctly used, the clock is adequate to the use for which it is proposed.
