Looking for a reference for pressure drop for tremied concrete. Product is a minimally flowable sanded cement grout through a tremie pipe. Grout will flow from the pump through say 50 feet plus/minus of hose and then another 100 feet plus/minus of horizontal pipe and then into a cavity which needs to be completely filled. I am trying to estimate the pumping pressure required, maintaining minimal pressure in the cavity at the end of the tremie.
