What is the role of a bioprocess engineer in botechnology industry?
Process engineering helps obtain the specifics of a certain industrial process. In the biotech industry, the quality of the final product has a huge bearing on the right physical and chemical conditions being maintained.
Therefore, the industrial process has to be engineered in order to obtain product starting from raw material.
What is stronger a round steel pipe or a steel hollow square bar?
By stronger, we need to define the loading conditions of the rod or pipe. The strength of a rod or pipe is typically evaluated with axial, transverse (bending), and torsion loads.
With the same diameter and the same material, a solid rod is stronger than a hollow pipe. However, with the same weight and material, the hollow pipe is stronger than a solid rod.
Because a hollow pipe is lighter than a solid rod at the same diameter, the hollow pipe would have a larger diameter in order to match weights with the solid rod and a larger diameter rod or pipe is stronger than a smaller diameter one.
How do you calculating sand for 1M3 comcrete?
Simply calculate volume of sand as you calculated volume of cement to be used, just don't multiply it with 1440, divide by 50 as in case of calculating cement.
you will get your answer in m3 of sand.
Civil Engineering is simply one of the discipline of engineering which deals with study of construction, design and maintenance of civil structures. For designing, planning to end of construction to maintenance its all about civil engineering. For more precise and clear definition you can visit http://www.thecivilengg.com
How many points needed for civil engineering?
To receive a degree in civil engineering, you need to complete for years in this discipline. The usual minimum number of credits needed for graduation is 130 credits. However, other colleges could require a different amount above this number.

How long were the Roman aqueducts?
The longest Roman aqueduct still standing is 90 km (57.5 mi) long, or 132 including its side channels. Other long ones include a 95 km aqueduct in Cologne (Germany) and a 91 km one in Rome.
What is the specification for silt content in sand?
first of all take the sample of the sand and insert it into a measuring jar,
then add water as per required,then add half spoon salt for better setting time.
shake the jar slowly....and wait for 10 minutes.
after 10 minutes you can see the different layer of the actual sand,silt and water.
for calculating the SILT CONTENT:-
silt divide by total height .that means sand+silt=total height. multiply by100 for percentage.
you can calculate silt content after 3 hr. also.
What is habitual reinforcement?
Habitual behavior is behavior that you do regularly and routinely. The behavior is comfortable and rewarding so it is easy for people to repeat it. A change in a situation or a cue typically starts the behavior.
What is the weight of 50x50x5 mm mild steel angle per meter length?
What is the weight of 50x50x5 mm mild steel angle per metre length? Density mild steel is 7.85 g/cm3
Volume is 2x(4.5x0.5x100)+(0.5x0.5x100)=475 cm3
Weight is 7.85x475=3728.75 g (per metre).
What material was used in the construction of The Richmond Bridge?
The "Richmond Bridge" London, England. The design is a stone arch bridge constructed of Portland stone, construction started 1774 and completed 1777.
The "Richmond Bridge" Richmond, Tasmania. The original name was "Bigge's Bridge and was constructed of sandstone, construction started in 1823 and completed in 1825.
When should a arch bridge be used?
The Arch was invented by the Romans. It makes a very sturdy construction, while making it lighter, and using less materials than the standard way of building. The weight of the story above resting on the top of the arch is transferred down each leg to the ground, instead of pressing on the lower story. The Arch is also what makes a Dome. Just think of 360 arches running through a common point at the top. The entire weight of the Dome is transferred to the walls of the building, and down into the ground.
Why was the Hoover Dam called the Boulder Dam?
Answer this question…
How can you calculate water velocity from flow rate or diameter of pipe?
if u r talking about presuure drop then it can be easily calculate with the help of relation 4flv*v/2gd
in that f is the friction factor which is different for vraious type of flow for that u have to search a good book of fluid mechanics, v is the velocity. length of pipe and d is diameter of pipe
Why concrete cube has high strength than cylinder?
Reasons for concrete cube to have greater compressive strength as compared to cylinder is
What is the Difference between load bearing and frame structure?
Trusses and frames are both composed of triangular members connected at joints.
In a truss, the joints are pin type joints and the members are free to rotate about the pin. As such, a truss cannot transfer moments and members are subjected to only axial forces (tensile and compression).
On the other hand, members of frames are connected rigidly at joints by means of welding and bolting. Therefore the joints of frames can transfer moments in addition to the axial loads.
In a practical setting, you may see trusses with no flexibility in joints, but it is still acceptable to analyse them as a perfect truss.
In order to calculate the extension of the cable we must first calculate the strain. Strain is related to Young's modulus using the following relation:
E = σA / εA
Where:
E = Young's Modulus
σA = Axial Stress
εA = Axial Strain
Therefore to calculate the strain, we must first calculate the axial stress in the cable:
σA = Force / Area
The cross sectional area (CSA) of the cable is equal to:
CSA = (pi(d2))/4 = pi x r2
CSA = pi(0.0036)2
CSA = 4.0715x10-5 m2
Axial Stress = (500 x 9.81) / 4.0715x10-5
σA = 120471449.98 Pa
Axial Stress = 120.47144998 MPa
Strain of cable (εA) = Axial Stress / Young's Modulus
εA = 120.471x106 / 210x109
εA = 5.736735713x10-4
To calculate the extension of the cable:
εA = Extension / Original Length
Therefore:
Extension = εA x Original Length
= 0.0045893885704 m
Is civil engineering the same as structural engineering?
Civil engineering covers a broader spectrum. Civil engineering students study Structural engineering, water engineering, Geotechnical engineering (soil mechanics) and Traffic and Transport engineering. With a civil engineering degree, graduates have the opportunity to and are qualified to work in any of the above fields, or they can persue further studies in one particular area, and therefore obtain more thorough and specific qualification in that area, such as structural engineering.
Nominal mixes are those proportioned by the volume of the main ingredients and usually written in order of the ingredients thus Cement:Sand: Coarse aggregate (stone, chippings). So a 1:3:6 is a nominal mix containing 1 volume of cement, 3 volumes of sand and 6 volumes of coarse aggregate.
Gauge boxes are generally used to batch the ingredients. The problem with these types of mixes is that the quality of the concrete is entirely dependant on the quality of the materials. In other words, if you use the same gauge boxes to weigh ingredients from different sources, you will most likely have different concrete qualities.
Designed mixes on the other hand are specified as a grade the producer of the concrete has to achieve usually in terms of compressive strength but may include other criteria (size of the stone, minimum amount of cement, flexural strength, air content etc). So a grade 30 concrete will be the same whether batched in Kansas City, Karachi, Kingston-Upon-Hull or Kinshasa
What is the longest swing bridge in US?
According to Wikipedia encyclopedia, the Frankford Avenue Bridge in Philadelphia is the oldest (see: http:/en.wikipedia.org/wiki/Frankford_Avenue_Bridge). According to this article, the bridge was built in 1697 or 1698. It is also known as the Pennypack Creek Bridge, the Holmesburg Bridge, and the King's Highway Bridge (probably it's original name).
*Actually this answer is false. The oldest bridge in the US is the old stone arch bridge next to the jewel mill (glen mill) in Rowley, MA. Built in 1643 and is still in use today.
