Methane (ch4) at 25c, 1 atm enters a furnace operating at steady state and burns completely with 140% of theoretical air entering at 400 k, 1 atm. the products of combustion exit at 700 k, 1 atm. kinetic and potential energy effects are negligible. if the rate of heat transfer from the furnace to the surroundings is 400 kw, determine the mass flow rate of methane, in kg/s.

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
