INTERVIEW BASED QUESTIONS PART-06

 1.Name any four type of pipe fitting & it’s application.

 →

→Conduction: - It is heat transfer from one body to another body which is in physical contact with it .it is restricted to solid.

Eg. Heat flow through wall of furnace

→Convection: - It is heat transfer from one point to another point within a fluid by mixing of hot & cold portion of fluid. It is restricted by fluid. (liquid & gas)

Eg_ heating of water in beaker

Radiation: - It is heat transfer from one body to another body by electromagnetic waves., which not in contact with it, it is not required any medium.

Eg. Heat flow from sun to earth.

3.Give full form of COD, BOD, TDS, PPM, CGMP & GMP.

→COD-Chemical Oxygen Demand

→The amount of oxygen present in water consume during two hrs by the organic and inorganic contaminant

→BOD-Biological Oxygen Demand

→BOD is the amount of dissolve oxygen needed by biological organism to break down organic material present in one liter water during five days at 20 degree Celsius.

→TDS- Total dissolved solid

→PPM- Parts per million

→CGMP-Current good manufacturing practice.

→GMP-Good manufacturing practice.

→GLP-Good laboratory Practice.

6.What is soap?

→When fatty acid (or oil) heated with alkali like NaOH to produce salt is called soap.

→Soap are the anionic surfactant.

Oil or fatty acid + NaOH  → soap + glycerol

RCOOH + NaOH→ RCOONa +H2O

      F.A                                soap

7.Which product will obtain by hydrolysis of sucrose?

→Glucose & fructose

C12H22O11 + H2O →  C6H12O6 + C6H12O6

    SUCROSE                                  GLUCOSE         FRUCTOSE

8.CHEMICAL FORMULA OF SUCROSE & FRUCTOSE.

→C12H22O11 - sucrose     C6H12O6 – fructose

9.Write the main component of table sugar?

→SUCROSE(C11H22O11) is a main component.

10.Give the name of table salt?

→NaCl
