**Transcription for Educational Website****Problem Statement:**In an experiment aiming to measure the pipe roughness (ε), a pressure decrease of 40 kPa was measured across a pipe length of 1 m. The straight pipe has a constant inside diameter of 0.1 m. If the velocity of water (specific weight 9810 N/m³; kinematic viscosity: 1 x 10⁻⁶ m²/s) was 1 m/s, what is the absolute roughness of this pipe material?**Diagram Explanation:**The **Moody Diagram** included in the image is used to determine the friction factor in pipes for different flow conditions. - **Axes:** - The horizontal axis represents the Reynolds Number (Re), ranging from 10³ to 10⁸. - The vertical axis on the left is the Friction Factor, ranging from 0.01 to 0.1. - The vertical axis on the right is the Relative Pipe Roughness (ε/d), ranging from 5 x 10⁻⁶ to 0.05.- **Curves:** - The curves on the diagram show the relationship between the Friction Factor and the Reynolds Number for different values of Relative Pipe Roughness. - The chart distinguishes between different flow regimes: Laminar Flow, Transition Region, and Complete Turbulence.- **Materials Section:** - A table lists materials and their typical absolute roughness values (ε) in millimeters (mm): - Concrete, cast cement: 0.5 mm - Concrete, new smooth: 0.25 mm - Drawn Tubing: 0.0015 mm - Glass, Plastic Pipe: 0 mm - Steel, rusted: 0.15 mm - Steel, rusted old: 3 mm - Steel, encrusted with limestone: 1.5 mm - Steel, rusted or forged: 0.45 mm - Water mains, old: 3 mm**Answer Options (Multiple Choice):**- ○ 0.050 mm- ○ 0.025 mm- ○ 0.500 mm- ○ 0.100 mmThe reader is expected to use the information provided in the problem statement and the Moody Diagram to calculate the absolute roughness of the pipe material.

Hi, I need help with this question please. Thank you. A cantilever thin-walled cylindrical tube of inner diameter ? = 30cm and thickness ? = 1cm is subjected to a torque T and internal pressure p as shown below. The free end of the tube is closed. Strain gauges A and B mounted on the surface of the cylinder give readings ?? = 7.5 × 10^−6 and ?b = 19.7x10^−6, respectively. The bar is made of steel having Young's modulus E=200 GPa and Poisson's ration ? = 0.3. a) Determine the torque, T, and internal pressure, p. b) Determine the absolute maximum shear strain ???? at point C.
A calibration test of a 12.7 mm circular sharp-edged orifice in the vertical side of a large tank showed a discharge of 587 N of water in 81 seconds at a constant head of 4.70 meters. Measurement of the water jet showed that it traveled 2.35 meters horizontally while dropping 30.50 centimeters. Determine the three orifice coefficients and draw the figure. Note: determine each coefficient independent from the other coefficients, solve them as equal to the ratio of the actual quantity to the theoretical quantity. No credit points for direct formula substitution solutions.
