The half-angle of the nozzle convergent cone section, , can range from 20 to 45 degrees. The divergent cone half-angle, , varies from approximately 12 to 18 degrees. The conical nozzle with a 15-degree divergent half-angle has become almost a standard because it is a good compromise on the basis of weight, length, and performance.
Commonly used method of accelerated depreciation. Straight-Line Method (Cost of Fixed Asset - Residual Value) / Useful Life of Asset (in years) Easiest and most common method of depreciation. Units of Production [(Cost of Asset - Redidual Value) / Estimated Total Production] x Actual Production: Depreciation measured by how many units are produced.
Calculator to plot lines in Slope y-intercept form and Standard form. Step by step explanations are provided.
4. A measure of the rate of a reaction is its half life. One method of determining the half life of a first order reaction is to plot certain appropriate data. Sketch a graph that illustrates the application of such a method. Label each axis with its name and appropriate units, and show how the half life can be obtained from the graph.
To obtain the value of E ° for the overall half-reaction, we first must add the values of Δ G ° (= − nFE °) for each individual half-reaction to obtain Δ G ° for the overall half-reaction: Equation 19.55 Solving the last expression for Δ G ° for the overall half-reaction, Equation 19.56
This is called the half-life of 14 C. In general, the half-life for a first-order kinetic process can be calculated from the rate constant as follows. Let's now turn to the rate law for a reaction that is second-order in a single reactant, X. The integrated form of the rate law for this reaction is written as follows.
Problem 002-mj | Method of Joints Problem 002-mj The structure in Fig. T-02 is a truss which is pinned to the floor at point A, and supported by a roller at point D. Determine the force to all members of the truss.
