Civil Engineering Interview Questions & Answers

-:Civil Engineering Interview Questions & Answers:-

1. What are the reasons for building collapse?

Lack of time is a reason. Buildings also collapse due to weak foundations. Earthquakes, storms, and other natural disasters can also damage the structure of buildings and may cause them. Bombing or demolition of buildings is also another reason.

2. What are the applications of elasticity modulus?

As the word implies, "the modulus of elasticity" is related to the elasticity of a material or "flexibility." The value of the elasticity of the modulus is very important regarding the deflection of some of the materials used in the construction industry. The E value of light carbon steel is approximately 200 GPA for about 70 GPA for aluminum. It simply translates that aluminum steel is 3 times flexible.

3. How do you measure concrete?

Cubic feet, cubic yard, cubic meter


4. Which is the strong solid steel rod or hollow steel pipe?

On the basis of per pound, the steel pipe is strong in bending and the possibility of buckle in axial compression is less.


5. What is the total?

Aggregate is a component of composite material used to prevent compressive stress.


6. How do you calculate the power of a centrifugal pump?

In order to operate the pump, the power of the pump should be noted in HP (Horse Power) on the nameplate of the pump. It can be calculated also by the 3-phase electrical equation:

P (in Hp) = VI (1.7c) = rated volts x rated current x 1.73 /% capacity

If it is a consumer grade pump that operates at 120Vac, then the equation becomes P = VI, by simply multiplying the operating voltage, 120 x curt (which is the number after the letter "A".) Output power, which is actually Technically, electricity, but rated in GPM (gallon per minute), or caution should also be on the nameplate. If you have make, model and serial number (not necessarily) on the nameplate then you can You can call Customer Service Department As an application engineer, I have contacted countless manufacturers, and for the help of the service department, it is a big deal for them, they will be happy to answer your questions.


7. What is rigging?

In sailing, ropes are used to move around boats so that the boat moves in the right direction when the wind blows.

8. What is the full pressure?

Absolute pressure is simply the value of the plus atmospheric pressure plus the observed pressure.


9. How do we calculate the absolute pressure?

Absolute gauge pressure is equal to plus atmospheric.


10. What is the gravitational flux?

The flow of gravity is the fluid flowing due to the forces of gravity and not for an applied pressure head. In the Bernoulli equation, pressure is dropped from the word, and only the conditions of height and velocity are included.
