A Venturi meter measures flow rate by means of a pipe, this is achieved by infinitesimaling the pipe and measuring the reversion in pressure, using a water manometer, at the narrow section compared to the wider section of the pipe. A Pitot tube is an instrument expend to measure the swiftness of a fluid in a steady flow. The tube has ii entrances, the first entrance faces the flow, the oncoming flow causes the fluid to move in the manometer, this distance elicit 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 abide be combined using the Bernoulli compare to calculate the change 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 exit measure the static and stagnation pressures of the airflow, the Pitot leave alone be manoeuvred across the pipe and further readings of pressure go forth be taken to calculate the radial velocity profile. legitimate argument will be blown through the Venturi meter; a water manometer will measure the pressure balance across the narrow sect! ion 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, browse it on our website: BestEssayCheap.com
