- Water flows through a pipe shaped as shown here. The pressure at the lower end of the pipe is 304 kPa and the fluid velocity is 4.00 m/s. The upper end of the pipe is 0.600 m higher and the cross-sectional area is 1/3 of the area at the lower end. Calculate the velocity at the upper end of the pipe.Calculate the pressure at the upper end of the pipe.A pipe made of two joined sections with different diameters of 1.0 and 4.0 inches, respectively. An incompressible fluid flows through this two section pipe. How will the speed of the fluid flow through the 4.0-inch section relate to that through the 1.0-inch section? (Answer in terms of v4-inch = [factor] x v1-inch.)Many cities have water tanks raised high off the ground to produce pressure for their residence. If one such water tank had a diameter of 4.40 m and its water level being 20.7 m above the ground. What would be the pressure at ground level if the water was not being used? (static)If at ground level a faucet had an opening with a diameter of 2.00 cm, how fast would the water come out of the faucet?
- rn=0.17 cm (nozzle radius)rh=0.95 cm (garden hose radius)Q=0.65 L/s (flow rate through the hose) Calculate the maximum height (in centimeters) to which water could be squirted with the hose if it emerges with the nozzle removed, assuming the same flow rate.xzvsdzfserfasefawsdawefsefdHydraulic systems utilize Pascal's principle by transmitting pressure from one cylinder (called the primary) to another (called the secondary). Since the pressures will be equal, if the surface areas are different then the forces applied to the cylinders' pistons will be different. Suppose in a hydraulic lift, the piston of the primary cylinder has a 2.1-cm diameter and the piston of the secondary cylinder has a 25.5-cm diameter. -What force, in newtons, must be exerted on the primary cylinder of this lift to support the weight of a 2250-kg car (a large car) resting on the secondary cylinder?
- Water flows in the system shown below. The flow exits the pipe at a speed of 4.0 m/s.(a). What is the water pressure when it exits the pipe?(b). What is the height of the column of water?With Bernoulli's principle, is there any other reason as to why the pressure of the fluid decreases with an increased velocity other than using the equation and conservation of energy? Why does the fluid pressure decrease? With an airplane wing, how does the air above the wing move faster and therefore provide less pressure, and why does this result in lift?A hydraulic system where a force f=5N is exerted on the left piston of area a=2m2. This is the result of an upward force being exerted on a larger piston of area A=100m2 on the right. a) What is the added pressure applied to the fluid by the force f? b) What is an upward force applied to the large piton?
