- Q1. Laws of thermodynamics.
- Ans.
Laws governing energy and its transformations in physical systems.
First law: Energy cannot be created or destroyed, only transferred or converted.
Second law: Entropy of a closed system always increases over time.
Third law: Absolute zero cannot be reached.
Applications in engineering, physics, and chemistry.
Examples: heat engines, refrigeration, combustion, chemical reactions.
- Q2. Principle of steam ejectors.
- Ans.
Steam ejectors are devices that use steam to create a vacuum by entraining and compressing gases or vapors.
Steam ejectors work by using a high-pressure steam jet to create a low-pressure zone, which draws in gases or vapors from the surrounding area.
The entrained gases or vapors are then compressed and discharged through a diffuser, which increases their velocity and reduces their pressure.
Steam ejectors are commonly u...
- Q3. Working of heat pump.
- Ans.
Heat pump is a device that transfers heat from a lower temperature to a higher temperature.
Heat pump works on the principle of refrigeration cycle.
It consists of four main components: evaporator, compressor, condenser, and expansion valve.
The refrigerant absorbs heat from the low-temperature source (air, water, or ground) in the evaporator and gets converted into a gas.
The compressor then compresses the gas, which incr...
- Q4. What is grinding ?
- Ans.
Grinding is a process of removing material from a workpiece using an abrasive wheel or belt.
Grinding is used to achieve high dimensional accuracy and surface finish.
It is commonly used in manufacturing industries for finishing operations.
Different types of grinding machines are used for different applications such as cylindrical, surface, and centerless grinding.
Grinding can be done manually or with the help of compute...

- Q1. Difference between Star/Delta starter for motor?
- Ans.
Star/Delta starter is used to reduce the starting current of a motor.
Star connection provides high starting torque but high starting current
Delta connection provides low starting torque but low starting current
Star/Delta starter uses both connections to reduce starting current and provide sufficient starting torque
Used for large motors to prevent damage to motor and electrical system
- Q2. CV calculation of control Valve?
- Ans.
CV calculation of control valve involves determining the valve's flow coefficient.
CV is calculated using the formula: CV = Q / (SG * sqrt(dP))
Q is the flow rate, SG is the specific gravity of the fluid, and dP is the pressure drop across the valve.
CV is used to select the appropriate valve size for a given application.
Factors such as valve type, trim size, and pressure drop affect the CV value.
CV calculation is importa...
