Page 177 - Constant of an engine is found by multiplying the area of the piston in square inches by the speed of the piston in feet per minute and dividing the product by 33,000. It is the power the engine would develop with one pound mean effective pressure. To find the horse-power of the engine, multiply the MEP of the diagram by this constant.
Page 424 - Oyclopsadia, worth in itself, for purposes of reference, at least a thousand volumes, is within the reach of all — the clerk, the merchant, the professional man, the farmer, the mechanic. In a country like ours, where the humblest may be called to responsible positions requiring intelligence and general information, the value of such a work can not be over-estimated.
Page 73 - ... is the same as that which a heavy body would acquire in falling from the height of an atmosphere composed of the gas in question of uniform density throughout.
Page 172 - ... of time. The first of these spaces is equal to the versed sine of the arc described by the moon in the same time, because that versed sine measures the translation of the moon from the tangent, produced by the centripetal force, and therefore may be computed, if the periodic time of the moon and its distance from the centre of the earth are given. The last space is found by experiments with...
Page 265 - Let 17 times the length of the grate in inches be divided by the square root of the height of the chimney in feet, and the quotient is the area for the aperture at the top of the chimney in inches.
Page 174 - To ascertain the nominal power by this method, multiply the square of the diameter of the cylinder in inches by the cube root of the stroke in feet, and divide the product by 47 ; the quotient is the number of nominal horses power of the engine.
Page 161 - ... inches =distance of the piston from the end of its stroke when the exhausting-port behind it is opened.
Page 195 - Multiply the square of the diameter of the cylinder in inches by the length of the stroke in inches, and by 171; and divide the product by the diameter of the driving-wheels in feet.
Page 23 - Multiply the complete divisor by the second figure of the root and subtract the product from the dividend.
Page 159 - ... any cover on the exhausting side, the port before the piston will be closed before that behind it is opened; and the interval between the closing of the one, and the opening of the other, will depend on the quantity of cover on the exhausting side of the valve. Again, the position of the piston in the cylinder, when these ports are closed and opened respectively, will depend on the quantity of cover that the valve has on the steam side. If the cover is large enough to cut the steam off when the...
