Civil Engineering

Civil Engineering is a profession of designing and executing structural works that serve the general public, like houses, buildings, roads, etc. A Civil Engineer is an engineer trained in the design and construction of public works, such as bridges or dams, and other large facilities.

What is the world's largest concrete batch plant?

The Erie Strayer MG-12CP2, I believe, has the highest production rate of any concrete batch plant. It is used for mass concrete placements that require 700+ cubic yards of concrete delivery per hour.

Why does not use other material instead of steel for concrete work?

Because of the thermal compactablity of the steel the material is used in concrete

How do you analysis stress in flexible pavement using kenpave software?

Hi!

The stress analysis of Flexible and Rigid pavements in KENPAVE is highly flexible and easier than any other softwares.

All you have to do is to input the geometric properties of pavement and material characteristics such as Modulus, Poisson ratio of individual layers, design traffic in Msa, wheel load, tire pressure and co-ordinates at which stresses, strains and deformations are required.

You can perform any number of permutations by varying the layer thickness and material properties to find the impact on the results.

This software can also be used for the design of Overlays especially flexible overlays as it can perform non-linear analysis too. Design of semi-rigid pavements can be performed without any difficulty. It's really versatile.

The Fatigue and Rutting life equations are parametric in nature, hence needs proper calibration before use.

Can a sewer lateral cross over a water main?

Yes, but there are requirements for vertical distance between the sewer and water main (generally at least 18 inches) and materials of construction. One reference is the so-called 10 State Standards (Section 38.3). If you do not have access to this publication (e.g., you are a homeowner), check with your local building department.

Basic mass air flow calculation in pipe?

Mass flow in air can be calculated if you know the pressure drop across the pipe. Then it can be calculated using Darcy's Equation for Pressure,which is: P2-P1 = (4fLv*v)/d*2*g where, P2 & P1 are pressures at two points in pipe, f = friction factor, L= length of pipe, v = velocity of fluid, d = diameter of pipe, g = gravity. from this formula we can calculate the velocity and hence the flow rate.

What is per capita demand?

The amount of water required per head per day and it includes the domestic, industrial and commercial use

What is more common continuous or partial reinforcement?

partial reinforcement i reinforcing a response part of the time.

What is the bending moment diagram for a simple supported beam with udl and a point load not in the centre of the span?

The answer is not formulatic. There will be a parabolic shape from the dead load and a discontinuity at the point load.

What is priming in the centrifugal pump?

The centrifugal pump has to be filled with fluid before it can start to move fluid. They cannot suck fluid in by creating a vacuum in the pump chamber like some other types of pumps.

What is another name for industrial engineering?

Systems engineering and process engineering are both terms that are used as names for industrial engineering.

What is pipe earthing?

in this method a galvonise iron pipe of 38mm internal dia 2.5 mt lenght having 12mm dia holes on its surface

What Quantity of cement in mix Mp40 concrete?

  • Quantity of cement = 400 kgs
  • No.of bags = 8

What does a back hoe do?

A back how is a kind of digger that has two shovels &the shovel at the back is not big as the big rectangle shovel but it still moves lots of dirt. The back hoe does a very important job to build a house.

Difference between the civil engineering project and the building construction project?

Building is a structure and civil in water, sewer, storm drains as well as roads and bridges.

Can 50 mph winds break windows?

no it needs to be about 75-85 mph and over for windows to break...big windows break faster than smaller windows.
