I still think the amount the hourglass slows (given a small angle) will be nowehre near the amount expected from calcuating the force and friction.Ĭan we use a water analogy? If you maintained the top resevoir at an exact regulated pressure, and had a curved round glass hole at the bottom, how much would the flow rate change give a smallish angular change from vertical? I don't think much at all. The i Nam thc lc lists the instruments that were at the Khm Thin Gim: Sand clock (1822): 10 (NTL, p. And when vertical many grains still have friction on the curved glass sides, so the anglular change may not affect total friction as much as in a simple device. And gravity always being vertical the grains always exit and fall vertical, moving against ech other vertically, again given a smallish angle.Īnd even the grains that do "touch the sides" are hard grains touching a hard curved glass surface so the total friction will be very low (especially since many grains don't touch the sides).

That sounds logical but I think there is a lot more to it than that! For a start, the orifice is much larger than a single grain, so the majority of exiting grains don't touch the sides, they only touch each other, regardless of angles (given a smallish angle).
