a) Water (Densitywater = 1,000 kg/m3) flows through a pipe that narrows. At point A it is determined that the water flows with a velocity of VA = 93 m/s. At point B it is determined that the water flows with a velocity of VB = 193 m/s.What is the nagnitude of the difference in pressure between points A and B.
b)
Two trains pass each other. Train A is traveling 36 m/s east. Train B is traveling 23 m/s west. After the trains pass each other train A blows its whistle with a frequency of 578 Hz. What frequency does a person on train B hear? Assume 342 m/s as the speed of sound.
c) When a 0.427 kg mass is hung from a certain spring it stretches 0.155 m to its equilibrium position at a point P. If this mass is pulled down 0.11 m from point P and released, what is the magnitude of the maximum acceleration of the mass in m/s2?
d) A pipe with an internal diameter of 2.54 2.66 cm attaches to a hose with an internal diameter of 1.11 1.257 cm. It is determined that water flows through the pipe with a velocity of 0.755 0.803 m/s. With what velocity does the water flow through the hose?

Water (1,000 kg/m3) flows into a 10.2 cm diameter,
inlet pipe (a.k.a Zone 1) at a pressure of 1.671E5 Pa. The liquid
then flows out of a 8.7 cm diameter, open faucet situated 1.6 m
above the inlet pipe, a.k.a Zone 2.
a) Calculate the flow speed of the Water in
Zone 2.
b) Calculate the volume flow rate of the Water
in either Zone.

A liquid of density 1.33 × 103 kg/m3 flows steadily through a
pipe of varying diameter and height. At location 1 along the pipe
the flow speed is 9.09 m/s and the pipe diameter is 10.9 cm. At
location 2 the pipe diameter is 14.3 cm. At location 1 the pipe is
9.75 m higher than it is at location 2. Ignoring viscosity,
calculate the difference between the fluid pressure at location 2
and the fluid pressure at location 1.
