Method of Statement for Fire Fighting Works (Part-2)             8 Votes (5) Vertical risers Vertical risers shall be parallel to walls and column lines and shall be straight and in plumb. Risers passing from floor to floor shall be supported at each floor by MS angle with clamp as per specification of pipe support. The space in the floor cut outs around the pipes work may be closed using cement concrete (1:2:4 mix) or steel sheet, from the fire safety considerations, taking care to see that a small annular space is left around the pipes to prevent transmission of vibration to the structure. Riser shall have suitable supports at the lowest point. (6) Sprinkler Heads & Accessories Installation of sprinkler heads will be done after pipe work flushing is completed. Apply the PTFE tape only to the male portion of the sprinkler and install the upright sprinkler head using the wrench provided by the manufacturer, and in such a way that the arms are parallel t...

A  capacitor  is a device that stores  electrical energy  in an  electric field . It is a  passive   electronic component  with two  terminals . Capacitor Type Passive Invented Ewald Georg von Kleist Electronic symbol The effect of a capacitor is known as  capacitance . While some capacitance exists between any two electrical conductors in proximity in a  circuit , a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as a  condenser  or  condensator . [1]  This name and its  cognates  are still  widely used in many languages , but rarely in English, one notable exception being  condenser microphones , also called capacitor microphones. The physical form and construction of practical capacitors vary widely and many  types of capacitor  are in common use. Most capacitors contain at least two  electrical conductors  often in t...
