Nadivalaya is an equinoctial sundial more analogous to the European sundials. It has two circular dials in the plane of the Equator - a North facing one and a South facing one.Construction of the instrument:
Unlike usual sundials fall when Nari Valaya Yantra (Yantra Narivalaya Gola) - following - the following characteristics in mind:There is a double sundial - the small building has on both the front and on the back of a sundial. Only the northern disc dates from the time of Jai Singh, the southern slice of red sandstone and white marble was replaced by his grandson Maharaja Pratab Singh.The dial is Narivalaya northern Uttar Gola, southern dial bears the name Narivalaya Dakshin Gola.Both are exactly parallel to each other.
The faces of the dials are highly inclined. You are exactly perpendicular to the ramp of the neighboring Laghu Samrat Yantra.It is a Äquatorialscheibenuhr. Critical to the operation is the integration of the geometry of the Clock in the geometry of the Earth:
The rod-shaped hands of both discs is exactly parallel to the ramp of the neighboring Laghu Samrat Yantra and shows exactly on the celestial north or south pole.
It is normal to the dials The dials are so inclined to be parallel to the ground and thus to the celestial equator are. This means that the disks are tilted by 27 ° from the vertical, ie exactly at the latitude of Jaipur. For such a width that is still feasible, but would have to do in Hamburg already considerable contortions in order to read the disc may lower.And last but not least: the transverse axis of the dials are of course parallel to the latitude in the east-west direction.
