Σελίδα 185 - The horse power of a steam engine is given by the equation , plan = ~ where p = mean effective pressure in pounds per square inch, l = length of stroke in feet, a = area of piston in square inches, n = number of strokes per minute, or twice the number of revolutions per minute.
Σελίδα 189 - The lead is the distance between the edge of the valve and the edge of the port from which the valve is traveling when the piston is at the end of its stroke.
Σελίδα 25 - This is called the total heat of vaporization, or simply total heat. It is plain that the total heat is the sum of the heat of the liquid and the latent heat. That is, total heat = heat of liquid + latent heat.
