Ans: d A valve is suddenly closed in a water main in wl. The length of a pipe is 1 km and its diameter is 20 cm. Two pipes of same length and diameters d and 2d respectively are connected in series. It is a very informative and useful post thanks it is good material to read this post increases my knowledge.
Black Granite. Thanks a lot! Fluid Mechanics. Established in Thanks for this. When there is a viscosity change in supply there is also greater loss in the system. This means change in pump flow affected by the pressure change. One more example is, positive displacement pump has more or less constant efficiency, where centrifugal pump has varying efficiency rate. How Cavitation can be eliminated in a Pump? Which pump is more efficient Centrifugal pump or Reciprocating pump?
What is a radial-flow turbine? In a radial-flow turbine, steam flows outward from the shaft to the casing. The unit is usually a reaction unit, having both fixed and moving blades. What is the function of a thrust bearing? Thrust bearings keep the rotor in its correct axial position. What is a stage in a steam turbine? In an impulse turbine, the stage is a set of moving blades behind the nozzle. What is a diaphragm? They hold the vane-shaped nozzles and seals between the stages.
Usually labyrinth-type seals are used. One-half of the diaphragm is fitted into the top of the casing, the other half into the bottom. What are topping and superposed turbines? Topping and superposed turbines arc high-pressure, non-condensing units that can be added to an older, moderate-pressure plant. Topping turbines receive high-pressure steam from new high-pressure boilers.
The exhaust steam of the new turbine has the same pressure as the old boilers and is used to supply the old turbines. What is a combination thrust and radial bearing?Post a comment.
