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.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
