In 1772, John Smeaton used the results of his tests on various existing Newcomen cycle engines to design and build his own atmospheric steam engine.

It had a 52.0-inch diameter piston with a 7.0 ft stroke and operated at 12.5 strokes per minute with a mean effective pressure of 7.50 lbf/in2 . It produced a remarkably high duty of 9.45 million.

Determine the
