A Venturi meter measures flow rate by means of a pipe, this is achieved by specialiseing the pipe and measuring the transpose in pressure, using a water manometer, at the narrow section compared to the wider section of the pipe. A Pitot tube is an instrument implement to measure the stop number of a fluid in a steady flow. The tube has deuce entrances, the first entrance faces the flow, the onslaught flow causes the fluid to move in the manometer, this distance send away 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 tush be combined using the Bernoulli comparison 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 ordain measure the static and stagnation pressures of the airflow, the Pitot pull up stakes be manoeuvred across the pipe and further readings of pressure lead be taken to calculate the radial velocity profile. synthetic argument will be blown through the Venturi meter; a water manometer will measure the pressure rest 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 convention 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, entrap it on our website: BestEssayCheap.com
