Water is flowing in the pipe shown in the figure below, with the 8.10-cm diameter at point 1 tapering to 3.05 cm at point 2, located y = 11.0 cm below point 1. The water pressure at point 1 is 3.20 x 104 Pa and decreases by 50% at point 2. Assume steady, ideal flow. What is the speed of the water at the following points? (a) point 1 (b) point 2 m/s m/s

A sealed tank containing seawater to a height of 12.0 m also contains air above the water at a gauge pressure of 3.05 atm. Water flows out from the bottom through a small hole.  Calculate the speed with which the water comes out of the tank. Express your answer in meters per second.

Oil with a density of 890 kg/m³ moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P, = 1.95 × 104 Pa, and the pipe diameter is 8.00 cm. At another point y = 0.20 m higher, the pressure is P, = 1.15 × 104 Pa and the pipe diameter is 4.00 cm. (a) Find the speed of flow (in m/s) in the lower section. m/s (b) Find the speed of flow (in m/s) in the upper section. m/s (c) Find the volume flow rate (in m³/s) through the pipe. m3/s

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?

A water pipe having a 2.20 cm inside diameter carries water into the basement of a house at a speed of 0.792 m/s and a pressure of 240 kPa. If the pipe tapers to 1.44 cm and rises to the second floor 6.14 m above the input point, what are the (a) speed and (b) water pressure at the second floor? (a) Number i (b) Number i Units Units

Question 2. Water pipe with an inside diameter of 4.80 cm carries water at an ab- solute pressure of 5.60 x 10 Pa from the basement into the fourth floor of a house. The fourth floor is 9.50 m above the basement and the diameter of the pipe on the fourth floor is 2.50 cm and the water pressure is 4.25 x 105 Pa. a) Find the speed of flow as water enters from the basement. b) Find the speed of flow in the fourth floor. c) Find the volume flow rate through the pipe.
