Metrology of surface finish

In general terms, the application of scientific principles in the study of measurements is known as metrology. When speaking about measurement, it could be of time, length, microstructures, grain structures, internal crystal discontinuities, surface roughness, measurements of angles, height, width, and so on. While coming to the domain of mechanical engineering, metrology is considered the science of measurements of surface finish, length, surface texture, and angles.

The paragraph below contains more than one instance of false statements or incorrect logic.
In a short answer (50 words or less) based on transport and mathematical concepts, describe
at least two errors in this paragraph that leads to the faulty conclusion.
Consider a gas confined within a large sealed holding tank. Assume that the gas is stagnant
(in the continuum sense) so that v =
Q everywhere inside the tank. The continuity equation
Dp
Dp
-p(V.v) applies to this gas. Since v= Q the continuity equation reduces to
= 0.
Dt
Dt
Integrating this equation gives the result that the density of the gas must be constant at every
position inside the tank. Constant density means the gas is incompressible. Since everyone
knows
gases are actually compressible, the original assumption that y = 0 must be
incorrect. Thus, we conclude that it is not possible to have storage tanks full of stagnant
gas – there must always be some non-zero velocity.

a) Sydney tap-water has a fluid electrical conductivity (EC or σ) of approximately 210μS/cm. Express this in terms of Ohm metres (resistivity) and mS/m (conductivity). b) The fluid electrical conductivity (EC) was measured on a water sample first at 25 °C to 305 μS/cm, then later at 20 °C to 272 μS/cm. Assuming a linear relationship, calculate the EC at 10 and 30 °C. c) A 20 cm long cylinder with 10 cm diameter is filled with an undisturbed fully saturated sandstone core. A current (I) of 100 mA was passed through the cylinder and a voltage(V) of 10,700 V was measured. Calculate the resistance and the resistivity of the sample. d) If we further know that the porosity is 1%, can you estimate the fluid electrical conductivity?
A graduate student wants to use van der Waals' equation to express the pressure-volume- temperature relations for a gas.

Units and dimensions are important in any engineering analysis. This problem is about that. In an old heat transfer textbook, you found the following equation for some specific heat transfer problem. Ə²T Q + əx² λ ƏT Ət You know that T is temperature (K) and x is the x-coordinate, which is measured in meters. You also know that t is time (s) and the book uses as the symbol for thermal conductivity, whose unit is W/m.K. What must be the units of Q and B?

Wind tunnel test section km/h Model FD Moving belt Drag balance The aerodynamic drag of a new Volvo FH truck is to be predicted at a speed of 85 km/h at an air temperature of 25°C (p=1.184 kg/m³, u=1.849x10-5kg/m-s). Volvo engineers build a 1/2 scale model of the FH to test in a wind tunnel. The temperature of the wind tunnel is also 25°C. The drag force is measured with a drag balance, and the moving belt is used to simulate the moving ground. Determine how fast the engineers should run the wind tunnel to achieve similarity between the model and the prototype.
