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脳10kg/m3.

Short Answer

Expert verified

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

Step by step solution

01

The given data

  1. Density of blood isp=1.06脳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, 鈭�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:

鈭�p=1.06脳103脳9.8脳1.83=1.90脳104Pa

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

A boat with an anchor on board floats in a swimming pool that is somewhat wider than the boat. Does the pool water level move up, move down, or remain the same if the anchor is (a) dropped into the water or (b) thrown onto the surrounding ground? (c) Does the water level in the pool move upward, move downward, or remain the same if instead; a cork is dropped from the boat into the water, where it floats?

The intake in Figure has cross-sectional area of0.74m2and water flow at 0.40m/s. At the outlet, distance D=180mbelow the intake, the cross-sectional area is smaller than at the intake, and the water flows out at 9.5m/sinto the equipment. What is the pressure difference between inlet and outlet?

A small solid ball is released from rest while fully submerged in a liquid and then its kinetic energy is measured when it has moved 4.0cmin the liquid. Figure 14-40 gives the results after many liquids are used: The kinetic energy is plotted versus the liquid density, and sets the scale on the vertical axis. (a)What is the density?(b) What is the volume of the ball?

Water is moving with a speed of 5.0msthrough a pipe with a cross-sectional area of 4.0cm2. The water gradually descends as the pipe cross-sectional area increases to 8.0cm2.

(a) What is the speed at the lower level?

(b) If the pressure at the upper level is 1.5脳105Pa, What is the pressure at the lower level?

In Figure, the fresh water behind a reservoir dam has depth D=15m. A horizontal pipe 4.0cmin diameter passes through the dam at depth d=6.0m. A plug secures the pipe opening.

(a) Find the magnitude of the frictional force between plug and pipe wall.

(b) The plug is removed. What water volume exits the pipe in 3.0h?
