A car with two people traveling down the road has a measure of 100 kg in a VELOCITY of 5M/F the carpools over and picks up two people the measure of the car is now 150 kg what is the new MOMEENTUEN if the VELOCITE is stays the same question

Which best represents the law of conservation of mass ?

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
