Answer:

a) A suspended floor is a ground floor with a void underneath the structure. The floor can be formed in various ways, using timber joists, precast concrete panels, block and beam system or cast in-situ with reinforced concrete. However, the floor structure is supported by external and internal walls.

b) Soil exploration consists of determining the profile of the natural soil deposits at the site, taking the soil samples and determining the engineering properties of soils using laboratory tests as well as in-situ testing methods

c) Bulking in sand Occurs When dry sand interacts with the atmospheric moisture. Presence of moisture content forms a thin layer around sand particles. This layer generates the force which makes particles to move aside to each other. This results in the increase of the volume of sand.

d) In a nutshell, bearing capacity is the capacity of soil to support the loads that are applied to the ground above. It depends primarily on the type of soil, its shear strength and its density. It also depends on the depth of embedment of the load – the deeper it is founded, the greater the bearing capacity.

What is storage tank stratification?
Artist 52 [7]

Answer:

Stratification is the process of arranging the different elements classification in a specific manner.

In the storage tank, hot water and cold water create a specific layer and coexist between them for the process of stratification. Thermal storage and heat storage exchanger are the types of storage tank, in which the stratification process take place.

The density of the cold water is more as compared to hot water. Then, due to this the cold water sink to the bottom and hot ware rises up in the storage vessel. In this way, the water gets heated and the stratification process take place in the tank.

A certain part of the cast iron piping of a water distribution system involves a parallel section. Both parallel pipes have a di
Bezzdna [24]

Answer :

<h3>Flow rate in pipe B is = 0.3094 \frac{m^{3} }{s}</h3>

Explanation:

Given :

Length of pipe A L_{A}  = 1500 m

Length of pipe B L_{B} = 2500 m

Flow rate through pipe A Q_{A}  = 0.4 \frac{m^{3} }{s}

Diameter of pipe D = 30 \times 10^{-2} m

Velocity from pipe A,

  V _{A} = \frac{Q_{A} }{A}

  V _{A} = \frac{0.4 \times 4 }{\pi ( 30 \times 10^{-2} )^{2}  }

  V_{A}  = 5.66 \frac{m}{s}

Here, head loss is same because height is same.

    h_{a} = h_{b}

L_{A} V_{A} ^{2} = L_{B}  V_{B} ^{2}

V_{B} = \sqrt{\frac{1500}{2500}}    (5.66)

V_{B} = 4.38 \frac{m}{s}

Now rate of flow from pipe B is,

Q_{B}  = V_{B} A

Q_{B}  = \frac{\pi }{4}  (0.3)^{2} \times 4.38

Q_{B} = 0.3094 \frac{m^{3} }{s}

Define the following terms: data, database, DBMS, database system, database catalog, program-data independence, user view, DBA,
nalin [4]

Answer:

data - Any form of value in a column of a table in a relational database.

DBMS - Short for Database management system, which is a software that can be used to create, manipulate and view databases, e.g. MS SQL Server.

database system - Same as DBMS.

database catalog - Place where the metadata of a Database including its tables, users etc. exists, e.g. date created, size, number of columns etc. Also known as Data Dictionary.

program-data independence - Program-data independence refers to the design of keeping different levels of database (external, logical and physical) separate and loosely coupled from each other, for easier maintenance or modification work.

DBA - Short for Database Administrator, person responsible for maintaining the database. Its main responsibility is to keep the data clean and safe i.e. data doesn't contain wrong or invalid data, and is safe from viruses and is backed up.

end user - Anyone who is not directly interacting with a database, but through some software, like website or mobile application.

persistent object - An object of a class in a program, that interacts with the underlying database and is responsible for manipulating the database, the program is connected to.

transaction-processing system - A transaction process system is part of a software, responsible for making sure critical business transactions, like crediting or debiting money, either goes through cleanly or doesn't at all.
