Design Calculators - Mechanical

This calculator helps determine the **Total Dynamic Head (TDH)** required for a pump in a fluid transfer system. TDH is the total equivalent height that a pump must lift water, taking into account static head, friction losses in pipes and fittings, and pressure differences. It is a critical parameter for selecting the right pump for a given application.

The calculation considers:

• **Static Head:** The vertical distance the fluid needs to be lifted.
• **Friction Losses:** Energy loss due to friction within the suction and discharge piping, calculated using the Darcy-Weisbach equation.
• **Velocity Head:** (Optional, often negligible or accounted for in friction loss approximations for simple calculators) The energy associated with the fluid's motion.
