Rank in order, from largest to smallest, the pressures at a, b, and c in FIGURE Q14.2. Explain.

Short Answer

Expert verified

The pressure in the decreasing order as Pb > Pc> Pa

Step by step solution

01

Given information

Three points (a,b and c) are given in the tank with different height filled with liquid.

02

Explanation

We know that the pressure exert by a liquid in tank depends on height and density of the liquid.

They are related as

P = hÒÏg + Atmospheric pressure.

Where

P = pressure

h = height of liquid column above point

ÒÏ = density of liquid

g = gravitational acceleration

Here we can see pressure (P) depends on the height (h) as density is same.

From the figure we can see

hb > hc > ha

So the pressure will be in the same order

Pb > Pc > Pa

A 2.0mLsyringe has an inner diameter of 6.0mm, a needle inner diameter of 0.25mm, and a plunger pad diameter (where you place your finger) of 1.2cm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100.

A. What is the minimum force the nurse needs to apply to the syringe?

B. The nurse empties the syringe in 2.0s. What is the flow speed of the medicine through the needle?

Disk brakes, such as those in your car, operate by using pressurized oil to push outward on a piston. The piston, in turn, presses brake pads against a spinning rotor or wheel, as seen inFIGURECP14.74. Consider a 15kgindustrial grinding wheel, 26cmin diameter, spinning at 900rpm. The brake pads are actuated by 2.0-cm-diameter pistons, and they contact the wheel an average distance 12cmfrom the axis. If the coefficient of kinetic friction between the brake pad and the wheel is 0.60, what oil pressure is needed to stop the wheel in 5.0s5.0s?
