Page 690 - Notice the general condition of the boiler and its equipment and record such facts in relation thereto as bear upon the objects in view. If the object of the trial is to ascertain the maximum economy or capacity of the boiler as a steam generator, the boiler and all its appurtenances should be put in first-class condition.
Page 484 - CL are line pressure and sonic speed of the gas at £ -» — *, and y is the ratio of specific heat at constant pressure to specific heat at constant volume for the gas.
Page 398 - For the purposes of this specification, the yield point shall be determined by the careful observation of the drop of the beam or halt in the gauge of the testing machine.
Page 2 - Multiply the numerators together for a new numerator, and the denominators together for a new denominator.
Page 416 - If any number of forces acting at a point can be represented in magnitude and direction by the sides of a POLYGON taken in order, they are in equilibrium.
Page 693 - The coal should be weighed and delivered to the firemen in equal portions, each sufficient for about one hour's run, and a fresh portion should not be delivered until the previous one has all been fired. The time required to consume each portion should be noted, the time being recorded at the instant of firing the first of each new portion.
Page 694 - In tests for purposes of scientific research, in which the determination of all the variables entering into the test is desired, certain observations should be made which are in general unnecessary for ordinary tests.
