Quickly, efficiently and reliably calculate total dynamic head in the field with the TDH app from Rain for Rent.

Designed for engineers, field operators and technicians, it allows for estimation of hydraulic conditions required for pump systems, making it easy to find the right equipment.

Based on Hazen-Williams equations, simply enter the hydraulic parameters of your pumping system and the app will return the Total Dynamic Head (TDH).

Intuitive controls enable users to dynamically simulate any combination of pre-loaded valves and fittings, and automatically converts nominal pipe sizes to actual hydraulic radii for true precision.

Piping materials used in this calculator are compliant compliant with American Water Works Association Standards for municipal.
