What are some reasons for various errors in the open channel flow experiment(fluid mechanics)?

Can explain 5 point. What engineering sustainability do for contain toxic/ harmful material with an example... Thankyou..

Where is dewatering required. Explain its types along with its context and types of dewatering?

The following information is given about a vertical curve:
Station of VPI = 150+00.00 feet
Elevation of VPI = 2500.00 feet
L = 1000.00 feet
g1 = -3.0%
g2 = 1.0%
(a) Find the stations and elevations of the BVC and EVC.

(b) Also, what is the station and elevation of the lowest point of the curve?

(c) Calculate the first and second differences on the curve elevations of the full stations

Q. No 1). Differentiate between:
Laminar flow and turbulent flow
Reynolds number and Fraud Number
FPS system of units and SI system of units.

Explain each point in detail and provide figure or sketch to explain. Each symbol should be defined clearly.

Q. No 2). State and explain Bernoulli’s equation define each term of equation clearly.

Q. No 3. The pressure drop D_p over a length L of pipe is assumed to depend on the average velocity V, the pipe’s diameter D ,the average height h of the roughness elements of the pipe wall, the fluid density ρ ,and the fluid viscosity µ .Write a relationship between the pressure drop and the other variables. Use Indicial Method (Rayleigh’s Method) only.

Air Pollutant Concentrations and Factors Affecting Air Pollution Air inversions greatly affect local air quality because pollution is trapped. Assume an inversion occurs over a 75 m x 50 m surface area and there is no way for the pollutant to escape. There are 100 cars and each one produces 10.5 µg/s of carbon monoxide (CO). Part a [1 points]: What is the concentration (in ppm) after 1 hour if the inversion is at 150. m? Part b [1 points]: What is the concentration (in ppm) after 1 hour if the inversion is at 1,500. m? Part c [1 point]: Is the NAAQS exceeded in either case? The 1-hr concentration for CO should not exceed 35 ppm. Part d [3 points]: Describe three ways (natural or human-caused) that the concentration of CO would decrease.

Discuss the importance of protecting interior spaces from intrusion of air and moisture.

Items of importance in your discussion include:

• Impact to occupants
• Impact to interior building material
• Impact to exterior building material as air and moisture moves through the structure

Laboratory compaction test results for a cohesive soil are given in the following table:

Plot Diagram with labels and sample test labels

Specifications call for a fill dry density of 114 pcf and further require that the fill be compacted at optimum water content for the field compactive effort. For the following field density test results on a fill, explain how you alter the field placement operation:

1. ?_d = 115 pcf ; ? = 12.5 percent

2. ?_d = 112.5 pcf ; ? = 13.5 percent

3. ?_d = 110 pcf ; ? = 14.5 percent

4. ?_d = 111 pcf; ? = 17.3 percent
