Chapter 14: Q14P (page 407)

Calculate the hydrostatic difference in blood pressure between the brain and the foot in a person of height 1.83m. The density of blood is1.06×10kg/m3.

Short Answer

Expert verified

Hydrostatic pressure difference in blood pressure between the brain and foot is1.90×104Pa

Step by step solution

01

The given data

  1. Density of blood isp=1.06×103kg/m3
  2. Height of personh=1.83m
02

Understanding the concept of hydrostatic pressure difference

We can use the formula for hydrostatic pressure in terms of density, gravitational acceleration, and height to solve for pressure difference.Hydrostatic pressure is that, which is exerted by a fluid at any point of time at equilibrium due to the force applied by gravity.

Formula:

Net pressure applied on a fluid surface, ∆p=pgh (i)

03

Calculation of net hydrostatic pressure

Hydrostatic pressure difference in blood pressure between the brain and foot using equation (i) and the given values can be written as:

∆p=1.06×103×9.8×1.83=1.90×104Pa

Hence, the value of hydrostatic difference in pressure is1.90×104Pa

We have three containers with different liquids. The gauge pressure pgversus depth his plotted in Fig. 14-28 for the liquids. In each container, we will fully submerge a rigid plastic bead. Rank the plots according to the magnitude of the buoyant force on the bead, greatest first.

You inflate the front tires on your car to28psi. Later, you measure your blood pressure, obtaining a reading of 120/80 , the readings being in mmHg. In metric countries (which is to say, most of the world), these pressures are customarily reported in kilopascals(kPa). In kilopascals, (a) what is your tire pressure? And (b) what is your blood pressure?

A50kgobject is released from rest while fully submerged in a liquid. The liquid displaced by the submerged object has a mass of 3.00kg. How far and in what direction does the object move in0.200s, assuming that it moves freely and that the drag force on it from the liquid is negligible?

Figure 14-22 shows a tank filled with water. Five horizontal floors and ceilings are indicated; all have the same area and are located at distances L, 2L, 3Lorbelow the top of the tank. Rank them according to the force on them due to the water, greatest first.

Figure shows two sections of an old pipe system that runs through a hill, with distances dA=dB=30mand D=110 m. On each side of the hill, the pipe radius is 2.00 cm. However, the radius of the pipe inside the hill is no longer known. To determine it, hydraulic engineers first establish that water flows through the left and right sections at 2.50 m/s. Then they release a dye in the water at point A and find that it takes 88.8 sto reach point B.

What is the average radius of the pipe within the hill?
