Question

Accepted Answer

Answers to various technical questions related to engineering.

Forced convection involves external forces like pumps or fans to move the fluid, resulting in higher heat transfer compared to free convection where the fluid moves naturally due to density differences.
The color of a flame depends on the temperature and the chemical composition of the fuel. For example, a blue flame is hotter than a yellow flame.
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. This principle is used in various applications like airplane wings and carburetors.
A fluidized bed boiler is a type of boiler where the fuel is burned in a bed of inert particles, resulting in better combustion efficiency and reduced emissions.
A fluid is a substance that can flow and take the shape of its container. Examples include water, air, and oil.
