Required information A nozzle of inner radius 1.08 mm is connected to a hose of inner radius 9.20 mm. The nozzle shoots out water moving at 25.0 m/s. At what speed is the water in the hose moving? cm/s

Required information A nozzle of inner radius 1.08 mm is connected to a hose of inner radius 9.20 mm. The nozzle shoots out water moving at 25.0 m/s. What is the mass flow rate? g/s

Required information The volume flow rate of the water supplied by a well is 2.00 × 10−4 m3/s. The well is 37.0 m deep. The density of water is 1.00 × 103 kg/m3.Find the pressure difference the pump must maintain. kPa

Estimate the average blood pressure in a person’s foot if the foot is 1.46 m below the aorta, where the average blood pressure is 104 mmHg. For the purposes of this estimate, assume the blood isn’t flowing. The density of blood is 1060 kg/m3. mmHg

When a block of ebony is placed in ethanol, what percentage of its volume is submerged? The density of a block of ebony is between 1000 and 1300 kg/m3. The density of ethanol is 790 kg/m3. %

Consider an aluminum annular disk with an outer radius 63.2 mm and inner radius 7.9 mm. The mass of the disk is 464 grams (HINT: the parameters of the disk are the same as in the previous pre-lab). The disk is allowed to rotate on a frictionless table with the rotation axis at its center. The disk has a small pulley rigidly mounted at the top concentrically. The pulley's radius is 12.1 mm, and the mass of the pulley is...
