Summary:
volume flow rate is equal to the product of cross sectional area of
pipe and velocity of water flow.
And mass flow rate is the product of volume flow rate and density of water.

6A pipe has a cross-sectional diameter of 3 cm, which narrows to 1.5 cm. Water flows into the larger end of the pipe with a velocity of 2 m/s. a. What is the velocity (v) of water through the narrower end? b. If the "flow rate" (R) into the larger end is 10 cm3/s, prove what is the "flow rate" (out) if the pipe is further narrowed from 1.5 cm to 0.75 cm?

20. A cylindrical water tower of diameter 3.0 m supplies water to a house. The level of water in the water tower is 35 m above the point where the water enters the house through a pipe that has an inside diameter 5.0 cm. The pressure at the top of the water tower is I ATM and the water in the cylindrical tank flows slowly at a speed of 0.01 cm/s. At what speed does the water flow in the...

Water is flowing through a 10-cm diameter water pipe at a rate
of 0.2 m^3/s. Now a diffuser with an outlet diameter of 20 cm is
bolted to the pipe in order to slow down water that exits into the
atmosphere, as shown. Disregarding frictional effects, determine
the force exerted on the flange due to the water flow. Density of
water = 1,000 kg/m^3.

A cylindrical water-storage tank has a height of 8.3 m and a radius of 5.8 m. The storage tank is full of water but is vented to the atmosphere. The bottom of the tank is 33 m off the ground. A 14 cm diameter pipe runs vertically down from the tank and goes 1.5 m underground before turning horizontal. The water flow in the horizontal pipe is 79 L/s. A) What is the water pressure (gauge) in the horizontal pipe...

There is an oil of 730 kg/m3 density is streaming in an
horizontal pipe of variable cross area. The oil is siphoned through
the pipe at a constant volume flow rate of 2.8 l/s. How long will
it take to siphon 1700 kg of oil through the pipe?
t = Unit in min
The left‑end cross segment of the pipe has a range of 6.1 cm,
what is the speed of the oil at which it streams trough this cross...

A cylindrical tank is being filled with water. The tank is initially empty but then water begins to flow into it at a rate of 62.00 kg/min. There is a small hole of radius r = 0.7000 cm at the bottom of the tank where water can escape. Because the flow rate of water leaving the hole is initially at a slower rate than water entering the tank, the water level rises. The average velocity of water leaving through the...
