- Biot Number - The Biot Number is a dimensionless quantity in heat transfer comparing internal and boundary layer heat resistances. Calculate Biot Number using this tool.
- Leak Rate - Calculate the rate of fluid leakage or accumulation using volume, time, and pressure differentials with the Leak Rate formula.
- Linear Elasticity - Hooke's Law - Hooke's Law formula calculates the force needed to extend or compress a spring by some distance. This calculator helps understand the behavior of springs and elastic materials.
- Moment of Force - The moment of a force produces rotation and is defined as the product of the force and the perpendicular distance from the point to the line of action of the force.
- Sludge Viscosity - Calculate sludge viscosity based on density and shear rate with this online calculator. Understand the resistance to flow of sludge.
- Volume of a Solid of Revolution - This formula calculates the volume of a solid of revolution obtained by rotating a circle around its axis.
- Young's Modulus - Young's Modulus is a measure of the stiffness of a material. It relates the stress and strain in the linear elasticity regime of a uniaxial deformation.
- Young's Modulus Calculation - Calculate Young's modulus (elastic modulus) using this online tool. Enter the stress and strain to find Young's modulus.
