What is latent heat of LPG?

Because LPG is a mixture, the value of the latent heat will depend on the exact composition of the mixture. The main components of LPG are:propane - C3H8propylene (propene) - C3H6isobutane - C4H10n-butane - C4H10butylene (butene) - C4H8Since LPG is usually mostly propane and butane, a rough estimate would be in the range of the values for these two components. Note that latent heat is dependent on temperature as well. for the purposes of this answer we will use 30 °F (near the boiling point of butane at atmospheric pressure)Hvap(propane @ 30 °F) = 163 BTU/lbHvap(butane @ 30 °F) = 166 BTU/lb


What makes an electric arc furnace electrode break?

Electrode are some times broken due to: -1) Electrodes making contact with a none metallic object as they are being hard pressed and ultimately broken. Electronic instruments are available to find this condition and take corrective measures to avert breakage of electrodes.2) Scrap falling against the electrode(also known as scrap cave-in or collapse)Above conditions are applicable for EAF3) Electrode breaking at joints due to incorrect jointing (Not having the correct torque applied to the sections being jointed)4) Rough handling prior to being used (While being moved or stored)5) If thermosetting thead lock are missing due to some reason or other,the same mishap may happen.6) Thread may have some entrapped external material which in turn damage the thread while torquing.7) If phase sequence is not correct, electrode will be loosened from the joint and may fall in the molten metal.vipin@vaibhavfurnaces.com
