Explain the basic requirement of pressure and capacity in water distribution system

QUESTION 3: POST INDUSTRIAL REVOLUTION PLANNING “Lewis Mumford was a visionary thinker who promoted ideas that are still relevant today.” 3.1 Compile a list of the development principles identified by Mumford which you think are still applicable today in South Africa.

Also, find the Ix, Iy, rx, ry, and J for an 8 inch tall, 6 inch wide rectangle with a 1 inch diameter hole drilled in it. The center of the hole is located 3 inches below and 2 inches to the right of the top left corner of the rectangle.

Describe a workplace you are familiar with.

For each type of hazard, describe an example of the hazard present in the workplace, and what controls are used to mitigate the danger associated with it. There should be an example of each type of control (Engineering, Administrative, and PPE) for each hazard.

Example: Grocery Distribution Center

Temperature Hazard: -25° Freezer
Engineering Control: The freezer is walled off from the rest of the perishable goods area
Admin Control: Personnel cannot work in the freezer more than 45 minutes at a time
PPE: Freezer suits, masks, gloves
Pressure Hazard: Ammonia lines for refrigeration
Engineering Control: Lines mostly run across the roof to keep them away from employees
Admin Control: Only authorized personnel are allowed in ammonia service areas
PPE: Enclosed eye protection, gloves, mask required when working on ammonia lines
Electrical Hazard: Forklift battery
Engineering Control: Battery is enclosed inside forklifts, except when being operated on by approved maintenance personnel
Admin Control: LOTO Program
PPE: Rubber gloves required when working on electrical components
Fire Hazard: Flammable products (such as lighter fluid, roach spray, etc)
Engineering Control: Aerosol room constructed inside the warehouse to contain all flammable products; in the event of a fire in the aerosol room, bay doors drop to enclose the fire.
Admin Control: All employees receive fire extinguisher and fire escape training.
PPE: Fire response team has fire suits, SCBA gear.
Toxic Material Hazard: Battery acid (from industrial truck batteries)
Engineering Control: Battery changing area located at far rear of shop, beyond grocery picking area and away from non-maintenance employees.
Admin Control: All employees perform pre-shift inspection of battery caps before boarding truck (if truck allows access to battery caps by non-maintenance personnel.)
PPE: Gloves, mask, goggles required for maintenance personnel when working on battery

1. Identify limitations on the application of Conservation of Energy.

Water flows from a large 4m detention basin (100m by 50m) along a 200mm diameter pipe for a distance of 100m at a slope of 1:200. The pipe centerline is 300mm above the base of the basin and it drains freely to a nearby channel. Calculate the steady flow rate if: (a) the flow is assumed ideal, (b) the pipe is considered smooth for the purposes of the Moody Diagram. (c) the pipe has a relative roughness of 0.006. (d) the time to empty the basin for case (c).

Why is it important for engineers to consider the environment in their projects?

Talk about Water Supply system and how it works and how its useful for use in 2 typed pages long in word.dox, you may provide pictures

Consider the contribution of the Romans to modern day water and wastewater engineering practice. Provide a summary of the key engineering concepts developed by the Roman public health engineers?

Explain various types of spikes with a neat sketchs.

Q1- What is the difference between centric and eccentric footings? How would they be used?

Q2- In addition to isolated footings, what are some other types of footings, and how/where are they used?

include the Harvard style reference for each answer.
