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.
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...
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...
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...

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
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...

Types of pumps include centrifugal, positive displacement, and axial flow pumps. Each has a unique characteristic curve.
Centrifugal pumps are commonly used in industrial applications and have a steep characteristic curve.
Positive displacement pumps are used for high viscosity fluids and have a nearly constant flow rate.
Axial flow pumps are used for low head, high flow rate applications and have a flat characteristic cu...
Distillation is a process of separating components of a mixture based on their boiling points. McCabe Thiele method is a graphical method used for designing distillation columns.
Distillation is used in various industries such as petroleum, chemical, and food processing.
There are two main types of distillation: batch distillation and continuous distillation.
McCabe Thiele method is used to determine the number of theoret...

Flow meter accuracy depends on various factors such as type of flow meter, fluid properties, and installation conditions.
The type of flow meter used affects its accuracy. For example, a differential pressure flow meter may have an accuracy of +/- 0.5% of the flow rate, while a magnetic flow meter may have an accuracy of +/- 0.25%.
Fluid properties such as viscosity, density, and conductivity can also affect flow meter a...
