lay down: William J Pape Student number: 110271743
Introduction The purpose of this experiment is to compare the use of a Venturi meter and a Pitot subway system in calculating the flow rate of air finished and through a pipe. A Venturi meter measures flow rate through a pipe, this is achieved by narrowing the pipe and measuring the flip-flop in pressure, using a water manometer, at the narrow section compared to the wider section of the pipe. A Pitot tube is an instrument utilize to measure the velocity of a fluid in a steady flow. The tube has two entrances, the first entrance faces the flow, the oncoming flow causes the fluid to move in the manometer, this distance fuel be measured and the stagnation pressure freighter be calculated, the second entrance is perpendicular to the flow, and this measures the static pressure, these two pressures can be combined using the Bernoulli equation to calculate the energising pressure and therefore the velocity of the flow (Munson).
For the experiment a pump provide blow air through the venturi meter, two of the above instruments lead be utilise as follows; an be Pitot tube will measure the static and stagnation pressures of the airflow, the Pitot will be manoeuvred across the pipe and further readings of pressure will be taken to calculate the radial velocity profile. logical argument will be blown through the Venturi meter; a water manometer will measure the pressure difference across the narrow section and the wider section of the pipe, this will be used to calculate the flow rate. The above procedure will be repeated for two different air speeds. The Bernoulli regulation describes the kind between velocity and pressure for an inviscid fluid in a steady flow; this is represented by the Bernoulli equation (Miller). The Bernoulli principle is clearly demonstrated in the experiment since it states that when the velocity of a fluid...If you want to get a full essay, order it on our website: Orderessay
