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.

Question

**Problem-4**

A liquid (Specific Gravity, S.G. = 0.9) flows downward through a vertical pipe as shown. Determine:
a) the pressure drop, Δp = p₁ - p₂
b) the volume flowrate (Q).

**Given:**
- h = 100 mm.
- Assume steady, incompressible, frictionless flow.
- (S.G.) Mercury = 13.6

**Diagram Explanation:**

- The diagram shows a vertical pipe with two sections: Section-1 and Section-2.
- Section-1 is at the top, where the liquid begins to flow downward.
- Section-2 is at the bottom, where the pipe expands, possibly affecting the flow characteristics.
- The vertical distance between the two sections is 0.6 meters.
- At the lower part of the diagram, there is a manometer containing mercury, used to measure the pressure difference between the two sections.
- The height difference in the mercury column is denoted as 'h' (100 mm) and is used to determine the pressure difference.
- Dimensions of the pipe sections are indicated: the width of Section-1 is 300 mm, while the width at Section-2 is 100 mm.

This setup can be used to calculate the pressure loss due to gravitational and flow effects using manometer principles.

Water flows inside a solid cylindrical pipe, which narrows as it goes up to a height h (see diagram below). The lower horizontal section has circular cross-sectional diameter d, whereas the upper horizontal section has diameter d/2. Let us denote A to be a point at the lower horizontal section and B to be a point at the upper horizontal section. The flow speed at A and B is uд and u, respectively. The pressure at A and B is PA and PB, respectively. РА UA Oom Ja d d/21 1 UB h (a) Assuming water to be incompressible, show that the flow speed at B is four times the flow speed at A. (b) Use Bernoulli's equation to find the drop in the water pressure from A to B. Express the result in terms of h, uд, the density of water p, and the acceleration of gravity g. (c) Above certain critical height h, vapour bubbles start to appear at the top horizontal section, which hinders water flow through the pipe. Explain why this happens.

Question 8 download image D The water in a large tank exits through a horizontal circular pipe of diameter D=0.01m and length L=94m. The centre of the exit of the pipe is h=1.0m below the water surface. We can assume that the flow entrance to the pipe is smooth so that there are no minor losses. The flow in the pipe is laminar, the friction factor can be assumed constant and can be found from h fD=64/Rep where the Reynolds number is based on the pipe diameter and mean flow speed in the pipe. Taking frictional losses into account, solve the resulting quadratic equation to calculate the speed of the flow out of the pipe. Give your answer in m/s to 2 decimal places.
