hi welcome to LMES          

      Today we are going to take one simple physics concept to real time experience . Bernoulli's theorem , we have read this in our 12th std . it is a two mark question .  

    Theorem ; 
         
                   Air or water , when velocity decreases the pressure will increases or when velocity increases the pressure will decreases  

       Real time application - spray , when we press the spray the dude will come out . In the same way Bernoulli's  theorem  

   
  when we pump  air in a high speed , so high velocity low pressure . in that diagram you can see a straw like structure in the bottle or jar or tin , inside the straw there will be no air so there is high pressure . for example in  cylinder when we open the tip the air inside the cylinder has high pressure and the air outside has low pressure , so when we open the tip the air will come out a lift will be generated . in the same the straw has high pressure the rubber bulb has lower pressure . so the spray water comes up to the rubber bulb . this is the real time application .                                  

 keep supporting me for more things .
