ABSTRACT/ SUMMARY The objective of this experiment is to determine the characteristics of open-channel flow. The types of flow to be determined are rectangular notch and triangular v-notch. Another objective of the experiment is to determine the discharge coefficients for both notches. The experiment for rectangular notch begins with admitting water to the channel. At this point‚ the water flow must be adjusted by using control valve in order to obtain heads (H). Throughout the experiment‚ five

Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer

Observation on U.S. Treasury Yields Date: Oct 10‚ 2012 Introduction In this paper‚ we establish three regression models on U.S. Treasury yields with two different maturities: three-month and one-year. Model 1 is to interpret the relationship between unemployment rates and the risk-free rates‚ which we choose the three-month T-bill interest rates. Model 2 is to evaluate the movement of short-term interest rates under pure expectation theory and liquidity premium theory as well as to compare

Linear graphs are when Y‚ which is Velocity‚ is proportional to the X variable‚ which in this case is time. Correlation coefficient of the velocity vs. time graph: 0.9815 Slope is the acceleration of this lab. The slope for the steelie are position in meters per seconds as shown by the graph. The velocity vs. time graph had a slope of 1.599 m/s. Conclusion: Annie Nguyen The purpose of this lab is to understand the motion of a ball bearing on an inclined plane through the graphical relationship

T-bill rates and Dow Jones Index (First Model) In order to present the relationship between the 3-Month T-Bill rates and Dow Jones index by our SAS output result‚ I constructed a single regression model: Y=β0+β1X (β0 = the intercept of 3-Month T-bill rate) (β1 = the slope of Dow Jones Index) 3-Month T-Bill rate=-0.04883+0.00000670*Dow Jones Index This means that when the Dow Jones Index increased by one point‚ the 3-Month T-bill rates will increase by 0.00067%.
