The question is incomplete: This is the complete Question

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.

yes

yes yes yes

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
