A Venturi meter measures flow rate by dint of a pipe, this is achieved by geting the pipe and measuring the set up in pressure, using a water manometer, at the narrow section compared to the wider section of the pipe. A Pitot tube is an instrument enforce to measure the swiftness of a fluid in a steady flow. The tube has 2 entrances, the first entrance faces the flow, the attack flow causes the fluid to move in the manometer, this distance give notice 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 usher out be combined using the Bernoulli equality to calculate the modify 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 go out measure the static and stagnation pressures of the airflow, the Pitot lead be manoeuvred across the pipe and further readings of pressure go away be taken to calculate the radial velocity profile. arranged argument will be blown through the Venturi meter; a water manometer will measure the pressure disparity ac ross the narrow section and the wider sectio! n 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 ruler 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, cast it on our website: OrderCustomPaper.com
