Motor Rewinding in Tetu

Where Tetu sits in Nyeri. Of the 3 constituencies in this county we hold confirmed elevation data for, Tetu is the highest — and those constituencies span 190 m between highest and lowest. That spread is the reason a county-level figure is not good enough to size against: two sites in Nyeri can need different machines for the same load.

Against the county headquarters. Tetu sits 125 m above Nyeri and runs 1 °C cooler on a design day. The difference is modest, but it is real, and it moves in the direction you would expect from the terrain.

Nearby, for comparison. Mukurweini at 1,747 m, Othaya at 1,873 m. Sites within a few kilometres of each other can still differ enough to matter, which is why we size against a measured site altitude rather than a district average.

Getting there. Tetu is roughly 96 km north of our Embakasi, Nairobi workshop in a straight line. Our mobile workshop covers all 47 counties, so attendance here is routine rather than exceptional.

How to read these figures. They describe Tetu, the settlement these measurements were taken at, which is not necessarily the centre of Tetu — treat them as a local reference point, not your site value. Derates are planning indications (about 1% per 100 m above 300 m, about 2% per 5 °C above 25 °C); the engine's own derate table governs. Elevation: GeoNames, via the Open-Meteo Geocoding API.
