    Hessam Nossoni April 8‚ 2013 Lab 6 Analysis of Open Channel Flow: Specific Energy Curve Summary In this lab‚ the flow rate over a broad crested weir is analyzed. First the flow rate is calculated by the use of the venturimeter. Two trails are performed to determine the specific energy curve for a given flow rate. In each trial‚ the height of water before and over the weir is measured. Two specific energy curves for each trail are graphed. Introduction Weirs are structures built across

    nature of the covalent bonds that form DNA (Carboni‚ 2007). Increasing the temperature causes the phospholipid bilayer to become more fluid which may allow molecules (that should not get in) to enter into the cells‚ thereby causing damage to the cell (Chandler‚ 2015). The extraction of DNA from cells is a very important aspect in the field of forensic biology. Extraction and purification of DNA are the first steps forensic biologists undertake in order to analyse DNA. If a sample is very degraded‚ DNA

    used for automotive purposes‚ offer significant advantages over current and proposed electrochemical battery technologies‚ both in performance and economy. An automotive propulsion concept is presented which utilizes liquid nitrogen as the working fluid for an open Rankine cycle. The principle of operation is like that of a steam engine‚ except there is no combustion involved. Liquid nitrogen is pressurized and then vaporized in a heat exchanger by the ambient temperature of the surrounding air.

    the real term is “Hydraulic Fracturing”. Hydraulic fracturing or (fracking) is the extraction of mainly natural gas. The process of fracking is pretty strait forward; the first thing you need to do is find your location where you are going to start fracking. Once you find your location you begin the frack process. “Fracking refers to the procedure of creating fractures in rocks and rock formations by injecting fluid into cracks to force them further open. The larger fissures allow more gas to flow

At low speeds‚ a symmetric winglet is at least as effective as a supercritical section winglet. So‚ there is no reason to use the more difficult to construct supercritical shaped winglet. It is found that there is no need to sweep the winglets for effectiveness at theses
