It thus becomes easy to tell the volume and pressure of steam required, which steam in its turn represents its equivalent of water which is to be evaporated from the boiler, and the boiler must be so proportioned, by the rules already given, as to evaporate this water freely.

Mr. Watt reckoned his boilers as capable of evaporating 10.08 cubic feet of water with a bushel or 84 lbs. of Newcastle coal, which is equivalent to 7 1/2 lbs.

I should then be in a position to know what pressure and volume of steam were required to overcome the resistance at the prescribed rate of motion; and, finally, I should allow a sufficient heating and fire grate surface in the boiler according to the kind of boiler it was, to furnish the requisite quantity of steam, or, in other words, to evaporate the requisite quantity of water.

Beyond the garden she saw, bathed in the sunlight, a field of corn, just in the ear, stretching for half a mile, its yellow, pollen-laden tassels overtopping the dark green mass of broad glistening blades; and in the distance, through the faint morning haze of evaporating dew, the line of the woods, of a still darker green, meeting the clear blue of the summer sky.

CONDENSED MILK.Condensed milk is made by evaporating milk in a vacuum to one fifth its original volume; it is then canned like any other food by sealing at boiling temperature in air-tight cans.

The banks of the river were more shapely, and the alternation of bushes and meadow, with the varying lights and shades on the distant peaks and the nearer slopes, would have seemed more than beautiful, if our wedged positions and the accompanying warmth had not somewhat evaporated our admiration.

A small array of white crockery shone from an open closet; and a squat-looking stove, which made the apartment agreeably warm, was smartly polished, and was evaporating cheerful music out of a bright teakettle.

Q.In other words you would recommend the inquiry to be restricted to the mode of evaporating a given number of cubic feet of water in the hour, instead of embracing the problem how an engine of a given nominal power was to be supplied with steam? A.I would first, as I have already stated, consider the actual power required to be produced, and then fix the amount of expansion to be adopted.

The only extra apparatus necessary is a couple of copper evaporating pans.

Setting aside 4 ounces of the filtered liquid for further experimenting, I packed the residue from the press into a conical glass percolator and exhausted with dilute alcohol, evaporating the percolate in a water-bath to two ounces, mixing with the 12 ounces of expressed juice and adding 2 ounces of alcohol.

A. A tubular boiler will require I/4 less grate surface, and will evaporate about 8 pounds of water to I pound of coal.

A.The evaporating power varies as the square root of the area of the flue, if the length of the flue remain the same; but it varies as the area simply, if the length of the flue be increased in the same proportion as its other dimensions.

I s'pose they jest nacherally evaporated durin' the night, maybe?" "Haines," said Silent sharply, "are you serious?

Salt is obtained by evaporating the seawater in small iron hand-pans (carahais), without previous evaporation in the sun.
