Hydraulic systems use liquid to transmit power while pneumatic systems use gas.
Hydraulic systems are typically used for heavy-duty applications such as construction equipment and aircraft landing gear.
Pneumatic systems are often used in lighter applications such as air brakes on trucks and buses.
Hydraulic systems are generally more powerful and can operate at higher pressures than pneumatic systems.
Pneumatic systems ar...
Hydraulic fluid is a liquid used to transmit power in hydraulic machinery.
Hydraulic fluid should have low compressibility to ensure efficient power transmission.
It should have good lubricating properties to reduce wear and tear of hydraulic components.
It should have good thermal stability to withstand high temperatures.
It should have good chemical stability to resist oxidation and corrosion.
Common examples of hydraulic...
Hydraulic fluids can be differentiated based on their viscosity, additives, and base oil.
Viscosity: determines the fluid's resistance to flow
Additives: improve the fluid's performance and protect against wear and corrosion
Base oil: can be mineral, synthetic, or vegetable-based
Examples: mineral oil, synthetic oil, water-based fluids
A boiler is a closed vessel used to generate steam or hot water for heating purposes. 5 tonne represents the capacity of the boiler.
Boilers are used in various industries such as power generation, heating, and chemical processing.
They work by heating water or other fluids to produce steam or hot water.
The capacity of a boiler is measured in tonnes, with 1 tonne equal to 1000 kg.
A 5 tonne boiler can produce 5000 kg of s...
Boilers are classified into different types based on their working pressure, fuel type, and application.
Fire-tube boilers
Water-tube boilers
Electric boilers
Gas boilers
Oil boilers
Solid fuel boilers
Condensing boilers
Non-condensing boilers

Flywheel stores energy while governor regulates speed.
Flywheel is a mechanical device used to store rotational energy.
Governor is a device used to regulate the speed of an engine or machine.
Flywheel is used to maintain the speed of an engine during the power stroke.
Governor is used to control the speed of an engine by adjusting the fuel supply or ignition timing.
Flywheel is commonly used in machines like steam engines,...
Buckingham pi theorem is a method to determine the number of dimensionless parameters in a physical problem.
It is used in dimensional analysis.
It helps to reduce the number of variables in a problem.
It states that if a physical problem involves n variables and k fundamental dimensions, then the problem can be expressed in terms of n-k dimensionless parameters.
For example, in fluid mechanics, the Reynolds number is a di...
To find deflection of conical bodies acting with axial load, use the formula for deflection of a cone under axial load.
Use the formula for deflection of a cone under axial load: delta = (P*L)/(E*A)
P is the axial load, L is the length of the cone, E is the modulus of elasticity, and A is the cross-sectional area of the cone
The deflection will be greater at the smaller end of the cone
Consider the material properties of t...
