calculation result for the flow coefficient Kv resulting from the given process conditions not taking into account the pressure loss of a pipe reduction at the inlet or outlet
highest pressure drop calculated at the given flow rate
highest travel time calculated for the opening or closing of a valve
pressure ratio at which the cavitation is acoustically detected
pressure differential ratio factor of a control valve installed without reducers or other fittings
plain text explaining conditions that have led to a design result for a control valve or have to taken into account when designing a control valve
fluid velocity at the entrance of a device
fluid velocity at the exit of a device
ratio of the flow rate through a control valve installed with attached fittings to the flow rate that would result if the control valve was installed without attached fittings and tested under identical conditions which will not produce choked flow in either installation
