Prandtl number and Schmidt number are dimensionless numbers used in fluid mechanics.
Prandtl number represents the ratio of momentum diffusivity to thermal diffusivity in a fluid.
Schmidt number represents the ratio of momentum diffusivity to mass diffusivity in a fluid.
Prandtl number is used to characterize the relative importance of heat transfer and momentum transfer in a fluid.
Schmidt number is used to characterize t...
Rankine cycle is a thermodynamic cycle used in power plants to generate electricity.
It is a cycle that involves the use of steam to generate power.
It consists of four processes: heating, expansion, cooling, and compression.
The cycle is named after William John Macquorn Rankine, a Scottish engineer and physicist.
It is commonly used in power plants that use fossil fuels or nuclear energy.
The efficiency of the cycle can b...
Diesel cycle is a constant pressure cycle while Otto cycle is a constant volume cycle.
Diesel cycle uses compression ignition while Otto cycle uses spark ignition.
Diesel cycle has a higher compression ratio than Otto cycle.
Diesel cycle is more efficient than Otto cycle due to higher compression ratio.
Otto cycle is used in gasoline engines while Diesel cycle is used in diesel engines.
Fourier law and Newton's law of cooling are both related to heat transfer.
Fourier's law states that the rate of heat transfer through a material is proportional to the temperature gradient across the material.
Newton's law of cooling states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings.
Both laws are used in various fields such as engineering,...

Transformer losses refer to the energy losses that occur during the operation of a transformer.
Transformer losses include copper losses and iron losses.
Copper losses occur due to the resistance of the transformer windings.
Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.
Copper losses can be minimized by using larger conductor sizes and reducing the resistance of ...
Efficiency of transformer is the ratio of output power to input power.
Efficiency is affected by factors such as core losses, winding resistance, and load impedance.
Efficiency can be improved by using high-quality materials, proper design, and regular maintenance.
Efficiency is expressed as a percentage and can range from 50% to 99% depending on the transformer type and application.
Non-sparking equipment and lights are used in hazardous environments to prevent explosions.
Non-sparking tools are made of materials that do not create sparks when struck or rubbed against each other.
Non-sparking lights use LED technology and are enclosed in a housing that prevents sparks from escaping.
These techniques are commonly used in industries such as oil and gas, chemical, and mining.
Examples of non-sparking too...
