flow-through it is zero 

flow is attained at a maximum value corresponding to critical exit pressure

it is not possible to increase the flow by increasing inlet pressure

it is discharging into the atmosphere

all of these

there is a pressure drop in the nozzle

fluid flows through the nozzle

pressure drops and fluid flows through the nozzle

there is no pressure drop and fluid does not flow through the nozzle
