pipe flow velocities

Types of Liquid Flow - The flow of liquid varies with speed of the liquid inside the pipes. Consider a pipe PQ through which a liquid flows. Let be the velocity of particles of liquid as shown in the diagram. If all the particles have the ..

When an object moves through a fluid, there will be friction due to the resistance of the material medium. This resistance increases with the velocity of the body as in the case of a rocket and aeroplane. Hence to minimize this friction due to the resistance of the medium, the bodies of ..

In the streamline flow of a liquid, every particle of the liquid follows the same path as the preceding particle. So, it has the same velocity (in magnitude and direction) as the preceding particle. The path of the particle is either straight or curved. Crowding of the pat..

Critical velocity is the velocity of a liquid flow upto which its flow is streamlined and after which its flow becomes turbulen..

Critical velocity is the velocity of a liquid flow upto which its flow is streamlined and after which its flow becomes turbulent. The critical velocity depends on coefficient of viscosity ' h ', density of the liquid ' r ', and radius of t..

sound is given by the formula The velocity of sound in iron was determined by two French investigators by striking one end of a long series of connected iron pipes with a hammer and measuring the time interval between the two sounds heard at the other end, the one transmitte..

. Let it be l 1 . This is called the first resonating length. The air column now, acts like a closed pipe and has the fundamental mode of vibration with a node at the surface of water and an antinode near the open e..

The Reynolds number is a pure number that determines the nature of flow through a pipe. The critical velocity 'V C ' is given by If the value of Reynolds Number N R lies between 0 to 2000, the flow of liquid is streamline or laminar (the layers of liqui..

Solar Water Heater - Here heat is absorbed by a blackened metallic pipe or plate and water circulated through these pipes gain heat. Solar Water Heater Usually copper is used and it is painted black from the inside. A large number of turns ensure that the water flows f..

. The amplitude of the board then becomes very large and the periodic force is said to have set the board in resonance. If the prongs of a vibrating tuning fork are held on the top of a pipe, the air inside it is set into vibration by the periodic force exerted on it, by the prongs. In ge..
