pressure losses in pipe

In this pipe, superheated water (170 o C) is sent down under 10 atm pressure. This melts the sulphur in the beds of the soi..

In an open pipe, when a compressed wave reaches the far end, the air at that point is, for an instant, at a pressure greater than the atmospheric pressure. Being an open end, the air there can vibrate with maximum freedom and so, it suddenly expands into the surroundin..

Summary - Pressure at a point in a liquid depends upon the depth and on the density of the liquid. The pressure at any depth in a liquid acts equally in all directions. Liquids always find their own level. Pressure applied at any point in a confined liquid is transmitt..

Mining of Sulphur - Frasch Process A Frasch pump consisting of a set of three concentric pipes is sunk deep into the sulphur bed Super heated water at 170 0 C under pressure is pumped in through the outermost pipe Sulphur in the sulphur bed melts due to its co..

Petroleum is brought to the surface by drilling a hole in the Earth's crust and sinking pipes deep down through the impervious cap rock. Natural gas first comes out under high pressure. Then, petroleum is pumped out, collected in tanks and transported, for further processing. ..

The transmission of power is made use of in hydraulic machines where a small force applied at one point is made to exert a much larger force at some other point. This principle is made use of in the working of a hydraulic press and hydraulic brake..

Glucocorticoids are hormones that regulate the metabolism of carbohydrates, proteins and fats. They have anti-inflamatory and antiallergic effects. They increase the blood-glucose level by converting proteins and fats into carbohydrrates, which in turn is converted to glucose. In case of excessive..

Slurry (mixture of equal quantities of biomass and water) is prepared in the mixing tank. The prepared slurry is fed into the inlet chamber of the digester through the inlet pipe. The plant is left unused for about two months and introduction of more slurry is stopped. During this p..

. Hence it is used in insulation of electric wires, manufacturing of squeeze bottles, toys and flexible pipes. When polymerization of ethylene is carried out in the presence of a catalyst at about 330 to 350 K, at atmospheric pressure, the polymer obtained has a linear structure..
