Notable Fact

In conjunction with Dr. Arnold J. Pacey, the society wrote, '‘The Measurement of Power in Early Steam Driven Textile Mills’'. James Watt based the premiums for using his patent steam engine on the power theoretically developed. Mill owners did not want to pay more than necessary, particularly when they were starting a new venture that might not have its full complement of machinery. The problem of determining the actual power output of the steam engine was solved around 1800 through the development of the ‘indicator’, a device that recorded the pressure of the steam in the cylinder against the movement of the piston . John Southern realised that the power of the engine could be calculated from the area of the graph described by the indicator.
