Today i am here to give you some learning on dynamic viscosity of water.
We know that when water contained in a beaker is set in to rotation with a glass rod or a finger ,it starts rotating in the type of co-axial cylindrical layers. When they cease stirring, the speeds of different layers are seen to decrease gradually and at last the water comes to rest.It shows that there has to be internal friction between layers of water, which tries to damage the relative motion between the layers
Sticky glue was made from mistletoe berries; used for lime-twigs to catch birds.
For example methanol is “thin” having a low viscosity, while vegetable oil is “thick” having a high viscosity. As a result, there is no alter in the average kinetic energy of the molecules remaining in the boiling liquid.
Relations between the forces motion of the body & acting on a body, formulated by Isaac Newton. The laws portray only the motion of a body as a whole & are valid only for motions relative to a reference frame. Usually, the reference frame is the Earth.
