friction losses in pipe flow

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 ..

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 same veloc..

A tank was filled with water flowing constantly from a pipe. People started using it after 60 minutes, when the quantity of water in the tank was 110 gallons. The scatter plot shows the quantity of water in the tank every 15 minutes. Describe the trend shown by the scatter plot...

Polishing the surfaces reduces the ruggedness between them. In an automobile when the piston moves in the cylinder the friction is reduced by polishing the surfaces, which are in contact. The jewel bearing and polished agate edges reduce the friction to a minimum. This is becau..

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..

Suppose a block connected by a spring is kept on a rough table as shown in the figure. The block is pulled aside and then released. It moves towards the centre A and has a velocity v 0 , as it passes through the centre. It goes to the other side of A and then comes back. This time, it passes throug..

The electricity produced from flowing water is called Hydroelectric power. The world's first hydroelectric power plant was set up in 1882 in Wisconsin USA. It had a very small output, supplying power only for about 250 light bulbs. But from this small start the production of hydroelectric..

The floating gas holder type of biogas plant has the following chambers/ sections: Mixing Tank - present above the ground level. Digester tank - Deep underground well-like structure. It is divided into two chambers by a partition wall in between. It has two long cement pipes: i) In..

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 liquid glide or..

If a plant cell is placed in a highly concentrated sugar or salt solution (i.e., hypertonic solution), water from the cell sap flows out due to exosmosis through the plasma membrane outside the cell. The loss of water from the cell sap causes contraction or shrinkage of th..
