Venturi Effect- Profound Lessons from a Road Rogue

Image
  I was sitting at the back of the class and playing book cricket. Our Physics teacher was working hard on explaining the Venturi effect. “Remember! Energy is neither created nor lost. It gets converted from one state to the other,” he said. “No loss, no gain,” I found the concept interesting.    Book cricket was my fiefdom. I made rules and decided when to start and finish the match. “Time for a drink break,” I told the cricketers, closed the book pitch, and gave all my ears to the teacher. “So, when the water in a pipeline comes across a choke point, the pressure inside the tube at the choke increases, and the velocity decreases. The moment it comes out of the choke, the pressure falls dramatically, and the speed of the water increases correspondingly. People designing the layout of long-distance pipelines incorporate it to install inline flow meters. It also makes sure that pipelines do not get clogged,” he said. Intuition told me it would be a sure question in the exa...

Qualifications or “Callification,” Selection and Retention Criterion

  Endless Efforts   “Callification?” Your efforts to find out what it means in the dictionary shall go in vain. I just made it up.  Patiently read through it; you will know what it means.     The three submersible pumps working continuously and in tandem could not fill the colony’s overhead tank. The employees kept the pump running. One pump ran dry far too long and burned itself out. The open well also ran dry. They told no one. Why should they? They had nothing to lose. I noticed the unusual activity and enquired. This had been going on for a few days. It should not have.   I did a quick calculation of the flow rates of the pumps, the capacity of the community tank, and the tanks over the individual houses. Considering the endless efforts of the pumps, all the overhead tanks should have been filled and overflowing. It did not happen. I concluded that there must be a leak somewhere in the pipeline. The large amount of water that leaked ...
