The flow rate (volume flux) through a pipe that varies in cross-sectional area is constant; that is equivalent to stating that the product of the cross-sectional area A and the speed v at any point is a constant. This result is expressed in ___________.
a)specific gravity
b)buoyant force
c)Bernoulli’s equation
d)the equation of continuity
Homework Answers
The correct option is Equation of continuity..
Reason : Equation of continuity states that the product of cross sectional area and speed at any point is constant. The product Av is volume flux or flow rate..

Water flows through a rectangular pipe at a speed of 3.73 m/s. The cross-sectional area of the pipe has a width W = 1.84 cm and a length L = 25.0 cm. The pipe then runs through a connection that changes the cross sectional area of the pipe to a circle. If the speed of water in the circular pipe is now 20.0 m/s, what is the radius R of the new pipe? Give your answer in cm. Note: ignore...

Consider steady flow through a layered soil column of cross-sectional area A as shown below. Soil 1 Soil a rm 2. The specific discharge through the column is v=Q/A Derive a formula for the pore water travel time through the column. The concept of an "equivalent" or "effective" homogeneous system is very important in groundwater studies. Let's replace the above layered system by an equivalent homogeneous system. The pore water velocity (seepage velocity) of the equivalent homogeneous soil column is...
