River meandering is the process of a river winding and curving along its course.
River meandering occurs when a river flows through a flat or gently sloping landscape.
It happens due to a combination of erosion, deposition, and the flow of water.
As the river flows, it erodes the outer banks and deposits sediment on the inner banks, causing the river to curve.
The speed and volume of water, as well as the type of sediment,...

Heat transfer coefficient changes with baffle spacing in heat exchangers. Other important factors include fluid properties, flow rate, and surface roughness.
Heat transfer coefficient increases with decreasing baffle spacing
Fluid properties such as viscosity and thermal conductivity affect heat transfer
Higher flow rates can increase heat transfer coefficient
Surface roughness can affect heat transfer by creating turbulen
Viscosity Index of lube measures its resistance to change in viscosity with temperature.
Viscosity Index (VI) is an important property of lubricating oils.
It measures the oil's ability to maintain its viscosity under different temperature conditions.
Higher VI means the oil's viscosity changes less with temperature, indicating better performance.
VI is calculated using kinematic viscosity measurements at two different tem...

Gibbs free energy is called free energy because it is the energy available to do work at constant temperature and pressure.
Gibbs free energy is the maximum amount of work that can be obtained from a system at constant temperature and pressure.
It takes into account both the enthalpy and entropy of a system.
If the Gibbs free energy is negative, the reaction is spontaneous and can do work.
Examples include the combustion o...
Maxwell's equations describe the behavior of electromagnetic fields.
There are four equations: Gauss's law, Gauss's law for magnetism, Faraday's law, and Ampere's law with Maxwell's addition.
Together, these equations explain how electric and magnetic fields interact and propagate through space.
Maxwell's equations are fundamental to the study of electromagnetism and have many practical applications, such as in the design...
