Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem …

Textbook Question

Chapter 10, Problem 74GP

Intravenous transfusions are often made under gravity, as shown in Fig. 10-55 O. Assuming the fluid has a density of 1.00 g/cm³_t at what height hshould the bottle be placed so the liquid pressure is (a) 52 mm-Hg, and (b) 680 mm-H₂o? (c) If the blood pressure is 75 mm-Hg above atmospheric pressure, how high should the bottle be placed so that the fluid just barely enters the vein?

(c) AP = 12.0 kPa. %3D 15-The Venturi tube shown in Figure may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (p= 7.00 X 10° kg/m³) through a hose having an outlet radius of 1.20 cm. If the difference in pressure is measured to be P1 - P2 = 1.20 kPa and the radius of the inlet tube to the meter is 2.40 cm, find %3D (a) the speed of the gasoline as it leaves the hose and (b) the fluid flow rate in cubic meters per second. xson e diiw abno sod ofT 66 2

(I) Engine oil (assume SAE 10, Table 10–3) passes througha fine 1.80-mm-diameter tube that is 10.2 cm long. Whatpressure difference is needed to maintain a flow rate of 6.2 mL/min ?

(III) A patient is to be given a blood transfusion. The blood is to flow through a tube from a raised bottle to a needle inserted in the vein (Fig. 10–55). The inside diameter of the 25-mm-long needle is 0.80 mm, and the required flow rate is 2.0 cm³ of blood per minute. How high h should the bottle be placed above the needle? Obtain p and ŋ from the Tables. Assume the blood pressure is 78 torr above atmospheric pressure. h FIGURE 10-55 Problems 66 and 74.
