- Q1. How many type of pump.
- Ans.
There are two main types of pumps: dynamic (centrifugal) pumps and positive displacement pumps.
Dynamic (centrifugal) pumps work by converting kinetic energy into potential energy, using a rotating impeller to increase the fluid's velocity.
Positive displacement pumps work by trapping a fixed amount of fluid and then forcing it into the discharge pipe.
Examples of dynamic pumps include centrifugal pumps, axial flow pumps,...
- Q2. How many type of gear.
- Ans.
There are several types of gears including spur, helical, bevel, worm, rack and pinion, and planetary gears.
Spur gears have straight teeth and are the most common type of gear.
Helical gears have angled teeth for smoother and quieter operation.
Bevel gears have cone-shaped teeth and are used to change the direction of rotation.
Worm gears have a screw-like appearance and are used for high torque applications.

- Q1. How does a diesel genrator work?
- Ans.
A diesel generator works by converting diesel fuel into mechanical energy which is then converted into electrical energy.
Diesel fuel is injected into the combustion chamber where it ignites and creates high pressure gases that push the piston down, creating mechanical energy.
The mechanical energy is then converted into electrical energy through the use of an alternator.
The alternator uses a magnetic field and a conduct...
- Q2. How a diesel engine works
- Ans.
A diesel engine works by compressing air in the cylinder, which heats up and ignites the fuel injected into the cylinder.
Air is drawn into the cylinder and compressed by the piston
The compressed air heats up and ignites the fuel injected into the cylinder
The explosion pushes the piston down, which turns the crankshaft and powers the engine
Diesel engines are more efficient than gasoline engines because they compress the...
- Q3. Why there is no differential in a train
- Ans.
A train doesn't need a differential because its wheels are fixed to the same axle and rotate at the same speed.
Train wheels are fixed to the same axle
Wheels rotate at the same speed
Differential is used in vehicles with wheels that rotate at different speeds
Differential allows for smooth turning
- Q4. Why petrol engines comparison ratio low when compared to a diesel engine
- Ans.
Petrol engines have lower compression ratios compared to diesel engines.
Petrol engines have lower compression ratios to prevent knocking or detonation.
Diesel engines have higher compression ratios to ignite the fuel without spark plugs.
Higher compression ratios in diesel engines result in better fuel efficiency and torque.
Petrol engines require lower compression ratios to accommodate the lower octane rating of petrol f...
