Q. How would you increase the power of an engine?
A. To increase the power of an engine, increase the speed; or get higher pressure of steam, use less expansion.
Q. How do you find the horsepower of an engine?
A. Multiply the speed of piston in feet per minute by the total effective pressure upon the piston in pounds and divide the product by 33,000.
Q. Which has the most friction, a perfectly fitted, or an imperfectly fitted valve or bearing?
A. An imperfect one.
Q. How hot can you get water under atmospheric pressure with exhaust steam?
