Water travels through a pipe at 7.50 m/s. The pipe expands from a crossectional area of 2.2 m2 to an area of 13.2 m2. What is the speed of the water in the second part of the pipe in m/s? How much is the pressure change in KPa as the pipe expands? The density of water is 1000 kg/m3. Enter a positive value for an increase in pressure, a negative value for a decrease.   Please WRITE out instead of typing, thank you.

A water intake at a pump storage reservoir (the figure) has a cross-sectional area of 0.585 m2. The water flows in at a speed of 0.596 m/s. At the generator building, at distance D = 224 m below the intake point, the cross-sectional area is smaller than at the intake and the water flows out at 8.64 m/s. What is the difference in pressure between inlet and outlet? Reservoir Generator building Intake D. Outlet- Number i Units

The input piston on a hydraulic lift has area A =1.5×10-4m2 and the lift plunger has area A. =4.5× 10-2m2. The car and plunger have a combined mass of 1900 kg. Pushing down the input piston lifts the car on the output plunger. A1 a. Find the hydraulic pressure needed to raise the car at constant speed. b. Find the force needed on the input piston. c. The input piston is pushed down 0.5 m. What is the work done on the car by the lift plunger? d. Explain how the lift can raise a car with such a small force.

A horizontal water pipe goes from a large diameter to a small diameter and then back to the first diameter as shown in the figure below. The level of water in the small vertical tubes provides us with information about the water pressure in the two different sizes of pipe. The inside diameter of the larger pipe is 2.70 cm and water travels through both sizes of pipe with a volume flow rate of 2.10 x 10-4 m³/s. Determine the inside diameter of the smaller pipe. m 8.00 cm * 4.00 cm

A pressurized tank supplies water to a hose. The hose rises h=1.3 m above the tank before spraying water a speed of 6.0 m/s. What is the pressure in the tank?  (Patm= 1.013x105)

A small blood vessels near the skin surface has a radius of 10um, a length  of 1um and the pressure  drop along the blood vessel is 2.50pa.The viscosity of blood is 0.0027pa.s. i. What is the  volume flow rate of blood through this blood vessel. What is the velocity  of blood flow? ii.Vasodilation causes the radius of this blood vessel to increase to 12um, while leaving the pressure drop along the vessel unchanged? What is the velocity of blood flow?

The water of a 14’ × 48’ metal frame pool can drain from the pool through an opening at the side of the pool. The opening is about h = 1.11 m below the water level. The capacity of the pool is V = 3880 gallons, the pool can be drained in t = 10.2 mins. P0 is the pressure of the atmosphere. ρ is the density of the water. a) Write the Bernoulli’s equation of the water at the top of the pool in terms of P0, ρ, h. Assuming the opening is the origin.  b) Write the Bernoulli’s equation of the water at the opening of the pool in terms of P0, ρ, h and v, where v is the speed at which the water leaves the opening. Assuming the opening is the origin.  c) Express the flow rate of the water in terms of V and t.  d) Calculate the numerical value of A in cm2
