Web1.2. Constant Head Tests [4] This paper deals with another subject meriting atten-tion; that is, constant head pumping in unconfined aquifers. In a constant head test (CHT), groundwater is withdrawn from a constant-head well at which a fixed water depth (the prescribed constant head) is maintained. Many landfills and
WebThe head loss that occurs in the components of a flow path can be correlated to a piping length that would cause an equivalent head loss. Head Loss. Head loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.
