physics fluid pressure

Fluid :- What* is a fluid ? A substance which flows from one, point to another is called, a fluid. Only liquids and gases exhibit flow motion. So they are called'fluids. Can a solid flow ? No. it cannot. Understand the difference between motion and flow. In a solid body all the particles are rigid..

Fluid thrust and pressure

A fluid always exerts a force on any surface in contact with it. The force so exerted is always normal to that surface. The total normal force exerted by a fluid on any surface is called the thrust due to the fluid on that surface. t> Since thrust is a force, it is expressed in newton. The dimensional fo..

fluid surface

What is Pressure ? The force acting normally on a surface is called thrust. The thrust Pressure? on unit area of the surface is called pressure. It is a scalar quantity. thrust Pressure = ___________ area The SI u..

experiments in fluids

Take a rubber balloon and attach it to the mouth of a water tap (fig. 6.5) Allow the water to flow into it . The balloon bulges out in all directions. Now punch it with a pin at different points at the same height around'the balloon. Note that water rushes out with equal force through all holes in all directions normal to the ..

gravitational forces and fluids at rest

In the last section we considered the forces on a parcel of fluid that was "at rest" and does not experience gravitational forces. We found that the pressure in any fluid in a container was the same in every direction at every location in the container. This is not so in fluids that experience gravita..

applied fluid mechanics

As we discussed in Section 15-8, ideal fluids are incompressible and flow in a streamlined fashion without experiencing friction forces. Water that flows in slow-moving rivers or large pipes acts like an ideal fluid. In this section we present a very useful equation that relates the pressure, velocity, and vert..

application of fluid mechanics

Pressure Cooker Pressure cooker is a device which raises the boiling point of water. Advantages of pressure cooker The water boils at a temperature below 100C on hills due to reduced pressure. Thus, cooking temperature of most things is not reached. When the same food materials are cook..

fluid level indicator

. At the entrance and exit, the fluid flows through the pipe with speed v a = \v"a I- But it flows through a narrow "throat" of cross-sectional area B with speed v B = | Vg\. A manometer connects the wider portion of the meter to the narrower portion. The change in the fluid's speed is accompanied by a change AP in the flu..

cerebrospinal fluid (csf)

It is a clear and colourless fluid that bathes the interior and exterior of brain and spinal cord (CNS). Cerebrospinal fluid is slightly alkaline (pH-7-33) fluid of 1 005 specific gravity that occurs in the ventricles of brain, central canal of spinal cord and subarachnoid space of meninges. Cerebrospinal ..

fluids & oscillations - questions answers

Fluids RE 15 -1 : Half the weight of the woman, (125 lb/2)(9.8 N/2.2 lb) = 300 N, is supported by her two spike heels. Let's say that each heel makes contact with 1 cm 2 = 10~ 4 m 2 of the floor. Then the pressure of her heels on the flgor is P = FIA = (300 N/10" 4 m 2 ) = 3 X 10 6 Pa. This estimate is..
