This represents the sensible heat Then to make the water boil at

pressure , or , in other words , to evaporate it , there must still be added 965.7

B. T. U. , thus 180 +965.7 = 1,145.7 , or in round numbers 1,146 heat units .

Side 109 - It has been seen that a heat unit is the quantity of heat required to raise one pound of water one degree in temperature...

Side 34 - A segment of a circle, is the figure contained by a straight line and the circumference which it cuts off.

Side 31 - When a straight line standing on another straight line makes the adjacent angles equal to one another, each of the angles is called a right angle ; and the straight line which stands on the other is called a perpendicular to it.

Side 297 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.

Side 129 - The water level should be as nearly as possible the same as at the beginning of the test. If it is not the same, a correction should be made by computation, and not by operating the pump after the test is completed.

Side 45 - The lower limit is specified for rubber-covered wires to prevent gradual deterioration of the high insulations by the heat of the wires, but not from fear of igniting the insulation. The question of drop is not taken into consideration in the above tables.

Side 34 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another : 16. And this point is called the centre of the circle.

Side 551 - One piston acts to give steam to the other, after which it finishes its own stroke and waits for its valve to be acted upon before it can renew its motion. This pause allows all the water valves to seat quietly, and removes everything like harshness of motion.

Side 138 - BTU per hour. It is also practically equivalent to an evaporation of 30 Ibs. of water from a feed water temperature of 100° F. into steam of 70 Ibs. gauge pressure.

Side 40 - A cone is a solid figure described by the revolution of a right-angled triangle about one of the sides containing the right angle, which side remains fixed.
