Read and feel sorry for lost human heritage : For 600 years, Nalanda was one of the best Universities in the world. Located in India, it attracted students from as far away as Greece who came to study in one of the greatest libraries the world had ever seen. It extended over three buildings that were up to nine stories high. The hundreds of thousands of books inside those buildings covered subjec ts as wide ranging as grammar, logic, literature, astrology, astronomy, and medicine. But many of the most precious texts were among the most important in Hinduism & Buddhism, and those religious tomes may have been what fanatic Bakhtiyar Khilji and his Muslim army were intent on destroying when they sacked the university in 1193. There were so many books that they burned for three months. and thousands of monks were burned alive and thousands beheaded.

Standards governing the design of fire pumps are updated every few years. This is done to ensure that these address the new design challenges and overcome the shortcomings of previous designs. In this light it would be quite interesting to look back over the last 10 years and gauge the important changes that have happened in these standards. A close analysis will reveal that the designs have significantly evolved for the better; these now ensure superior performance and safety. Here we will look back and see some of the major changes in the standard of fire pumps and their resulting benefits. 1. Torsion analysis for right angle gear drives For vertical shaft pumps that are right angle gear driven, a torsion analysis is mandatory. This helps to identify and eliminate any damaging stresses or liner resonant frequencies created from the operating speed range of the rotating equipment. This will help avoid any potential damage to the pump equipment. 2. The right diese
