A piston pushes 20 ∘C water through a horizontal tube of 0.23 −cm radius and 2.7 m length. One end of the tube is open and at atmospheric pressure. Determine the force needed to push the piston so that the flow rate is 105 cm3/s . The viscosity of water at this temperature is 1.0 ×10−3 N⋅s/m2. Express your answer with the appropriate units. Repeat the problem using SAE 10 oil instead of water. The viscosity of oil is 0.20...
Fire hoses used in major structure fires have inside diameters of 6.0 cm. Suppose such a hose carries a flow of 40.0 L/s starting at a gauge pressure of 2.2×106 N/m2. The hose goes 10.0 m up a ladder to a nozzle having an inside diameter of 2.8 cm. a. What is the pressure in the nozzle? b. What is the speed of water coming out of the nozzle?

Unfiltered olive oil must flow at a minimum speed of 3.0 m/s to prevent settling of debris in a pipe. The oil leaves a pump at a pressure of 87 kPa through a pipe of radius 9.4 mm. It then enters a horizontal pipe at atmospheric pressure. Ignore the effects of viscosity. A. What is the speed of the oil as it leaves the pump if it flows at 3.0 m/s in the horizontal pipe? Express your answer to two...

A large city waterline pipe has radius 6.2×10−2 mand feeds ten smaller pipes, each of radius 2.2×10−2 m , that carry water to homes. The flow rate of water in each of the smaller pipes is to be 6.0 × 10−3 m3/s, and the pressure is 4.00 ×105 N/m2. The homes are 11.0 m above the main pipe. What is the average speed of the eater in the main pipe? (Not 0.496 m/s) What is the pressure of the main...
Problem 4 (50 points) water is discharged from a reservoir at a rate of 18.103 m2/s using two horizontal cast iron pipes nected in series and a pump between them. The first pipe is 20 m long and has a 6-cm diameter, while the second pipe is 35 m long and has a 4-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged. Losses associated with the connection...
