Find the magnitude and the direction of the resultant force that acts upon the elbow which is located on the horizontal plane. Diameter of pipe at section (1) is D1=10 cm, pressure is P1=150000 Pa , the diameter at section (2) is D2= 5 cm and the discharge is Q=0.025 m3/s.(pwater= 1000 kg/m3) Use Formula: ∑f equal to pQv2-pQv1

Explain the relationship between metallurgical and materials engineering and other engineering disciplines.

Starting from the point (x0, y0) = (2,3) of the function f (x) = 4x ^ 2 - 4xy + 2y ^ 2, it is to choose to proceed according to the Steep Descent Method (x2, y2).

A cantilevered one way slab of effective span 1.5 m has an effective depth of 100 mm. The slab is provided with 10 mm dia. main reinforcement at 150 mm c/c spacing. Check the slab for deflection if, Ast required is 522.02 mm2. The grade of concrete is M20 and grade of steel is Fe 415.

The cement and concrete industry is a key link in the circular economy. Alternative fuels/raw materials in cement kilns, utilising recycled aggregates and cementitious industrial by-products in concrete and producing durable concrete structures assist in the circular economy. Example of fly ash production is shown in Figure 1. Discuss the use of any THREE new binders, waste materials and recycled materials (as ingredients) in concrete production and their suitable applications. Produce a ‘white paper’ (not more than 5 pages) and it should include the following:

(i) Identified 3 ingredients and a brief description of their production.

(ii) How these materials are used to produce certain grades of concrete.

(iii) Energy savings and carbon dioxide emissions of all ingredients.

(iv) Link with circular economy.

Between 2009 and 2050, as the world population is expected to increase by 2.3 billion, urban populations are projected to grow by 2.9 billion – from 3.4 to 6.3 billion (UNDESA, 2009). Urban areas are therefore expected to absorb all of the world’s population growth over the next four decades, while also drawing in some of the rural population. Furthermore, most of the urban population growth will be concentrated in the cities and towns of less developed regions that already face enormous backlogs in shelter, infrastructure, and services, as well as insufficient drinking water supply, deteriorating sanitation, and increasing environmental pollution. What would you say are the most important factors of water resources sustainability that must be studied to handle this urban growth, particularly in less developed regions? Please justify your answers in detail.
