Effect of the Variation of Initial and Back Pressure on the Economy of a Simple, High Speed, Automatic Steam Engine: A Thesis (Classic Reprint) - Hardcover
Synopsis
In this thesis, the author examines how initial and back pressure affect the economy of a small, high‑speed steam engine.
Through controlled experiments, the study shows how shifting pressures changes water use and thermal efficiency, with practical implications for how engines perform in real work.
The work details the setup, testing procedures, and the careful data collection that helps separate the effects of load, pressure, and exhaust conditions. It also compares results across two series of tests and explains how measurements were calibrated and corrected to ensure meaningful comparisons.- Learn how increasing initial pressure can lower water consumption up to a point, then level off.
- See how back pressure influences water rate and efficiency, with a straight‑line trend over the tested range.
- Understand the practical testing approach, including how heat in steam and steam quality are accounted for.
- Get a look at how uncertainties and potential sources of error are discussed and addressed.
