A liquid (ρ = 1.65 g/cm3) flows through two horizontal sections of

tubing joined end to end. In the first section the cross-sectional area is

10.0 cm2 , the flow speed is 275 cm/s, and the pressure is 1.20 x 105

Pa. In the second section the cross-sectional area is 2.50 cm2. Calculate

the smaller section’s (1) flow speed and (2) pressure.

(1) Smaller's section flow speed =

(2) Smaller's section pressure =

Step-by-step explanation:

Question 1

Using the continuity equation, we have that:

Question 2

Next, we apply Bernoulli's Equation

Let r = ρ(the density)

The pressure is given to us in its fundamental unit, Pa. So, we need to convert the speeds and density to their fundamental units.

≅

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
