Fluid mechanics - Assignment ExampleIntroduction When a gas undergoes motion, there are certain laws it must satisfy. Two of the basic laws pertain to the preservation laws for mass and skill. While the conservation of mass leads to Continuity Equation, conservation of energy gives us Bernoullis Principle. (1) Continuity Equation the amount of fluid volume per unit time must remain constant as the fluid cannot be compressed (no density variation) and the mass flowing in to a certain area per unit time must always be said(prenominal) to that going out from that area in exactly the same time. Thus, leading to the important equation Q = A1 ? u1 = A2 ? u2 .....(1) where A1 and u1 are the cross-sectional area and fluid velocity on an individual basis at the location 1 and A2 and u2 are those at 2 along the Venturi tube-shaped structure shown below. (2) Bernoullis Equation similarly, when we take into account the conservation of total energy of the water in the thermionic tube, which happens to be one of the most fundamental conservation principles in Physics, we obtain the Bernoullis equation. ... ic foreman or Pressure Head, denoting the energy due to the fluid pressure the 2nd term defined as Velocity Head, denoting the kinetic energy and the 3rd term named as say-so Head, denoting potential energy, combine together to give the total energy or Head of the fluid in motion. Apparatus Used (1) Venturi Tube or Venturimeter (2) Stopwatch (3) Graduated Beaker 1 2 3 4 5 6 7 8 9 10 11 Venturimeter or Venturi Tube Methodology criterion 1 Known volume of water (10 litres in the first case) is allowed to flow in through the inlet, located at impersonate marked as 1 Step 2 when the water flows through the Venturi Tube and goes out through the valve at 11, it is collected in the have beaker and the volume is noted down along with the total time taken to travel through the Tube. Subsequently, Q, the Volumetric Flow Rate is measured using the Eqn. (1) Step 3 simultane ously, the heights of the water columns in each of the 11 capillary tubes connected to the Venturimeter at 11 different locations are also observed guardedly and put the relevant column in the Observation Table 1 below Step 4 the Velocity Head and Pressure Head as given by Eqn. (2) are also calculated for different fluid velocities at different locations, and the values are tabulated in Columns 6 & 8 on an individual basis Step 5 finally, the total energy or Head of the fluid is measured just by adding the Velocity Head and the Pressure Head since the Potential Head remains unchanged Step 6 all the 5 steps mentioned above are repeated for 20 litres and 25 litres and the measurements are save in Tables 2 & 3 Step 7 bar diagrams are plotted for Evh, the Velocity Head, against the Tube Locations. Similarly, another graph is plotted for Esh, the Static Head, Vs the Tube
