Interview Questions with Answers
1. What is priming?
- Pump casing must be filled with liquid
before the pump is started, or the pump will not be able to function. If the
pump casing becomes filled with vapors or gases, the pump impeller becomes
gas-bound and incapable of pumping.
2. Types of pumps?
- Positive Displacement
- rotary lobe
pump, progressive cavity pump, rotary gear
pump, piston pump, diaphragm
pump, screw pump, gear pump,
Hydraulic
pump, vane pump
- Centrifugal Pumps
- end suction pumps, in-line pumps, double
suction pumps, vertical multistage pumps, horizontal multistage pumps, submersible
pumps, self-priming pumps, axial-flow pumps, regenerative pumps.
3. What is octane number in fuel?
- The octane rating of Gasoline
is measured in a test engine, and is defined by comparison with the mixture of 2,2,4-trimethylpentane (iso-octane) and heptane
which would have the same anti-knocking capacity as the fuel under test:
the percentage, by volume, of 2,2,4-trimethylpentane in that mixture is the
octane number of the fuel. For example, petrol with the same knocking
characteristics as a mixture of 90% iso-octane and 10% heptane would have an octane rating of 90.
4. What is added in LPG to detect leakage?
- Methyl Mercaptan
5. Pascal law ? Applications?
- Pascal's
law or the Principle of
transmission of fluid-pressure states that "pressure exerted
anywhere in a confined incompressible fluid is transmitted equally in all
directions throughout the fluid such that the pressure ratio (initial
difference) remains the same.
Application- Hydraulic jacks, Car lifts,
Fork Lifts
6. Can you transfer the heat energy from
cold body to hot body?
- Yes, with external work. Eg : Air
conditioner
7. What is hogging and sagging?
- Hogging
and sagging describe the shape
of a beam or similar long object when loading is applied. Hogging describes a beam which curves upwards
in the middle, and sagging describes a beam which curves downwards.
8. What Bernoulli’s Principle?
- In fluid
dynamics, Bernoulli's
principle states that for an inviscid flow,
an increase in the speed of the fluid occurs simultaneously with a decrease in pressure
or a decrease in the fluid's
potential
energy.
9. Difference between single acting and
double acting pump?
- In single-acting machines the compression
takes place on only one side of the piston; double-acting machines use both
sides of the cylinder for compression. The flow is continuous in double acting
and in single acting the flow is not continuous unless there is a surge vessel.
10. What is VSD?
- Variable Speed Drive
11. What is conduction, convection and
radiation? Give Examples?
- Conduction or diffusion
The transfer of energy between objects that are in physical contact
Convection

13. Classify Carbon Steels on basis of
carbon content?
Low-carbon
steels contain up to 0.30% C. The largest category of
this class of steel is flat-rolled products (sheet or strip), usually in the
cold-rolled and annealed condition. The carbon content for these
high-formability steels is very low, less than 0.10% C, with up to 0.4% Mn.
Typical uses are in automobile body panels, tin plate, and wire products. For rolled steel structural plates and sections, the carbon content may be increased to approximately 0.30%, with higher manganese content up to 1.5%. These materials may be used for stampings, forgings, seamless tubes, and boiler plate.
Medium-carbon steels are similar to low-carbon steels except that the carbon ranges from 0.30 to 0.60% and the manganese from 0.60 to 1.65%. Increasing the carbon content to approximately 0.5% with an accompanying increase in manganese allows medium carbon steels to be used in the quenched and tempered condition. The uses of medium carbon-manganese steels include shafts, axles, gears, crankshafts, couplings and forgings. Steels in the 0.40 to 0.60% C range are also used for rails, railway wheels and rail axles.
High-carbon steels contain from 0.60 to 1.00% C with manganese contents ranging from 0.30 to 0.90%. High-carbon steels are used for spring materials and high-strength wires.
Ultrahigh-carbon steels are experimental alloys containing 1.25 to 2.0% C. These steels are thermomechanically processed to produce microstructures that consist of ultrafine, equiaxed grains of spherical, discontinuous proeutectoid carbide particles.
