This experiment was conducted to investigate breathing using a dry portable spirometer each students are given disposable mouthpiece with spirometer (shared in a group) to measure vc, tv and erv this is done by exhaling air through the mouth piece in different ways (refer procedure) and record the reading. The predominant direction of water flow is determined by the concentration of the solutes (non-water molecules) inside and outside of the cell our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes better essays 512 words (15 pages) biology lab report essay - biology. Conclusion: from the results of the experiment, it can be concluded that the flow rate across an orifice depends upon several factors: 1- the cross sectional area of the orifice 2- the total head before the orifice 3- the type of the orifice 4- its sharpness. Lung capacity is how much air can fit into your lungs in one breath want to test your lung capacity enjoy our range of fun science experiments for kids that feature awesome hands-on projects and. Measurement techniques and to some principles of pipe flow in this experiment three basic devices – a pressure transducer, an orifice‐plate flowmeter and a paddlewheel an orifice plate is one of the most common flow measurement devices flow meter return water supply orifice plate pipe section pressure.

Essay about lab report essay about lab report 961 words oct 3rd, 2014 4 pages lab report: scientific method if there are 1000 meters in a kilometer, how many meters are there in 005 km 50 meters flow measurement in closed conduit a introduction knowledge of flow measurement in a closed conduit is very important, especially to. Volume flow rate (cubic meters per second) = duct area (square meters) × flow velocity (meters per second) in aviation, airspeed is typically measured in knots in weather stations with high wind speeds, the pitot tube is modified to create a special type of anemometer called pitot tube static anemometer. Measurements from pairs of transducers can be combined to yield a measurement of velocity in 1-, 2-, or 3-dimensional flow the spatial resolution is given by the path length between transducers, which is typically 10 to 20 cm.
Introducing measurements in the laboratory objectives a student runs 18752 meters in 542 seconds calculate his average velocity (or speed) measure and record the volume of water in the beaker 2 again, fill the same test-tube to the brim with tap water, then carefully transfer it to a 100-ml. Turbidity meters measure the amount of light scattered at a specific angle, and convert that reading into a turbidity measurement 16 some turbidimeters are designed to compensate for color absorption and high turbidities, while others are intended for precise and accurate readings at very low turbidity levels. Precision unless there is a digital display, always measure to one spot beyond the smallest unit of certain measurement of the tool for example, if you use a ruler that can accurately measure to the tenth of a centimeter, your measurement would be to the hundredth of a centimeter. According to the lecture notes, d = 42163112 meters corresponds to t = 86164 seconds and according to your calculations from the previous homework, d = 42163212 corresponds to t = 861643065 the relative errors in the distance d and the t for one revolution are d d relative = 000023717% and d t relative = 0000355717.
