The inlet volumetric flow rate is 100 L/min, then what is the exit temperature? You may assume ideal gas behavior, and neglect changes in kinetic and potential energy.
Tests reveal that a normal driver takes about 0.75 seconds before he or she can react to a situation to avoid a collision. It takes about 3 seconds for a driver on a cell phone to do the same.
If still a saturated mixture, what is the exit quality? You may assume negligible pressure drop through either stream, and neglect changes in kinetic or potential energy.
If the rods enter the oven at 30°C and leave at a mean temperature of 700°C, determine the rate of heat transfer to the rods in the oven in kW.
