How can I find the Total Dynamic Head (TDH) of one or more pumps?
Problem ID#: 90398
The Total Dynamic Head is basically the pump head - the head that the pump adds which overcomes both the "static head" (difference in upstream/downstream boundary conditions) as well as the "dynamic head" which is the headlosses in the pipes between.
If you are looking for just the dynamic portion, you would have to find the difference in elevation between the upstream and downstream boundaries (wet well, outfall, etc.), then subtract that from the total pump head.
