Diagram of the elements required to calculate TDHProper grit system pump selection requires calculating the Total Dynamic Head (TDH) of the overall grit system, and is based on the specific system layout. This estimator enables operators and engineers to effectively estimate the TDH of a system.

TDH is the total equivalent height that a fluid is to be pumped, taking into account friction and minor losses in the system piping. TDH includes total static head, which is the change in water elevation between the water level in the grit collection device and grit washing device, combined with headloss through the grit washing device and friction and minor losses in system piping.
