- A waste management company handles large dumpsters of construction debris. The sorting process starts by downloading the dumpster from the transport truck and then dumping its contents into a large hopper as shown below. The waste management plant uses a hydraulic cylinder arrangement to tilt the dumpster to the point that the force of gravity will empty the contents. The plant operator activates an electric pump that pumps hydraulic oil into the input piston at an absolute pressure of 2.50 x 106 Pa and drives the output plunger, which has a radius of 0.230 m. If the design of the dumping arrangement is such that the output plunger remains perpendicular to the floor of the dumpster, determine the torque the plunger creates about an axis at the end of the dumpster. Enter a number. Frect pressure to use for the pressure in the oil at the site of the input piston? According to Pascal's Law, how is the pressure in the oil at the site of the output plunger related to the pressure in the oil…I Review I Constants I Periodic Ta Water flowing through a 2.5-cm-diameter pipe can fill a 200 L bathtub in 3.3 min . ▼ Part A What is the speed of the water in the pipe? Express your answer in meters per second. ? V = m/s Submit Request AnswerA booster pump on a brake system designed to be used horizontally consists of two cylinders capped by pistons connected by a hose. The cylinders and hose are filled with an incompressible fluid. The system produces a mechanical advantage of six times; that is, the output force is six times as great as the input force. If the cross-sectional area of the input piston is 2.6 in2, how large (in in2) must the area of the output piston be? _____________in2
