Q1. Based on my BTP, define Reynolds number and its formula?

Ans.

Reynolds number is a dimensionless quantity used to predict fluid flow patterns and turbulence.

  • Reynolds number is calculated as the ratio of inertial forces to viscous forces.

  • It is used to determine whether a fluid flow is laminar or turbulent.

  • The formula for Reynolds number is Re = (ρVD)/μ, where ρ is the density of the fluid, V is the velocity of the fluid, D is the characteristic length of the flow, and μ is the dynamic viscosity of the fluid.

  • For example, a fluid flowing t...read more

Q2. Speak on "Radiation waste management" For 3-4 mins.

Ans.

Radiation waste management involves the safe handling, storage, and disposal of radioactive materials.

  • Radioactive waste can come from various sources such as nuclear power plants, medical facilities, and research institutions.

  • The waste is classified into different categories based on its level of radioactivity and half-life.

  • Proper storage and disposal methods include deep geological repositories, dry cask storage, and vitrification.

  • Regulations and guidelines are in place to e...read more

Q3. Compare Reynolds number of oil and water.

Ans.

Reynolds number of oil is higher than water due to its higher viscosity.

  • Reynolds number is a dimensionless quantity used to predict fluid flow patterns.

  • It is calculated using the fluid's density, velocity, viscosity, and characteristic length.

  • Oil has a higher viscosity than water, which means it resists flow more.

  • This results in a higher Reynolds number for oil compared to water.

  • Higher Reynolds number indicates more turbulent flow and mixing.

  • For example, the Reynolds number o...read more

Q4. Material used in Heat exchanger's fins.

Ans.

The material used in heat exchanger's fins is typically aluminum or copper alloys.

  • Aluminum and copper alloys are commonly used due to their high thermal conductivity.

  • Other materials such as stainless steel and titanium may also be used in certain applications.

  • The choice of material depends on factors such as cost, durability, and the specific application.

Q5. What is sinking fund method

Ans.

Sinking fund method is a way for a company to set aside money over time to repay a debt or replace an asset.

  • Sinking fund method involves regular contributions to a fund specifically designated for repaying debt or replacing assets.

  • The purpose of the sinking fund is to ensure that enough money is available when the debt matures or the asset needs to be replaced.

  • By using the sinking fund method, a company can avoid having to take out a large loan or use other sources of funding...read more

Q6. 3-2-1 principal of design

Ans.

3-2-1 principle of design is a rule of thumb for creating visually appealing designs.

  • 3 elements: primary, secondary, and accent

  • 2 fonts: one for headings and one for body text

  • 1 focal point: the most important element in the design

  • Example: using a bold primary color, a lighter secondary color, and a bright accent color

  • Example: using a sans-serif font for headings and a serif font for body text

  • Example: making the focal point larger and more prominent than other elements

Q7. 4.75 to 10 size of sieve

Ans.

4.75 to 10 size of sieve refers to the range of particle sizes that can pass through the sieve.

  • 4.75 to 10 size of sieve indicates the range of particle sizes that can pass through the sieve mesh.

  • Particles smaller than 4.75 will pass through, while particles larger than 10 will be retained on the sieve.

  • This range is commonly used in particle size analysis in industries like construction and mining.

Q8. Fool proofing of design

Ans.

Fool proofing of design ensures that the design is robust and can withstand errors or misuse.

  • Identify potential errors or misuse scenarios

  • Incorporate fail-safe mechanisms to prevent errors

  • Provide clear instructions and warnings for proper use

  • Conduct thorough testing and validation

  • Continuously monitor and improve the design

Q9. What is Grade of M20

Ans.

Grade of M20 refers to the mix ratio of concrete where M denotes mix and 20 represents the compressive strength in N/mm^2 after 28 days.

  • M20 concrete mix consists of 1 part cement, 1.5 parts sand, and 3 parts aggregate.

  • The compressive strength of M20 concrete after 28 days is 20 N/mm^2.

  • It is commonly used for residential construction like foundations, slabs, and beams.

Q10. What is Grade of M25

Ans.

Grade of M25 refers to the mix design of concrete with a compressive strength of 25 MPa.

  • M25 grade concrete is a mix design with a compressive strength of 25 MPa after 28 days of curing.

  • It is commonly used in construction for residential buildings, bridges, and pavements.

  • The mix proportion for M25 grade concrete is usually 1:1:2 (cement:sand:aggregate).
