To demonstrate that when a liquid flows through a tube with a constriction, the speed of the flow is increased and the pressure decreased in the constricted section. Comprises a horizontal glass tube of size 500 x 10 mm. length x bore, constricted in the center, with three short side tubes for the attachment of glass manometer tubes. Variation of pressure in various compartments of the tube can be determined by using the constant head device for sending the water through tube.
