A Venturi meter measures flow rate by dint of a pipe, this is achieved by shrinking 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 habituate to measure the hurrying of a fluid in a steady flow. The tube has devil entrances, the first entrance faces the flow, the attack flow causes the fluid to move in the manometer, this distance evoke be measured and the stagnation pressure freighter be calculated, the second entrance is perpendicular to the flow, and this measures the static pressure, t hese two pressures sens be combined using the Bernoulli comparison to calculate the energizing 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 entrust measure the static and stagnation pressures of the airflow, the Pitot give be manoeuvred across the pipe and further readings of pressure get out be taken to calculate the radial velocity profile. secerned argument will be blown through the Venturi meter; a water manometer will measure the pressure unlikeness 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 commandment 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 pr inciple is clearly demonstrated in the exper! iment since it states that when the velocity of a fluid...If you want to get a full essay, order it on our website: BestEssayCheap.com
