The Eisco Labs Fluid Pressure Apparatus demonstrates the transmissibility of fluid pressure using two brass cylinders (19mm and 38mm diameter) fitted with pistons and connected by a brass tube. The pistons feature leather packing for a tight seal and include rods for applying force. Mounted on a wooden base. Students observe how pressure applied to the smaller piston is transmitted equally to the larger piston, demonstrating Pascal’s principle and the basis of hydraulic systems. Suitable for physics classrooms studying fluid mechanics.
