Actual flow rate, direction, dispersity and dispersion coefficients of groundwater are achieved by the dispersion tests.

The actual flow reciprocating pump flow rate than theory, and with the increased pressure head decreases, which is due to leakage caused.

往复泵的实际流量比理论流量小，且随着压头的增高而减小，这是因为漏失所致。

The actual rate of flow is detected by means of an orifice plate; the pressure difference across the plate is a function of the rate of flow.

实际的流速由光阑测量，通过该光阑的压差是流速的一个函数。

"It is telling that the Department of Justice's charges against Kurt Mix surround efforts to cover up the fact that BP's public estimates of the oil flow rate were far lower than the actual flow rate, " the group said in a statement on the arrest.
