A segment of four-lane freeway (two lanes in each direction) has a 3% upgrade that is 1500 ft long followed by a 1000-ft 4% upgr
ade. It has 12-ft lanes and 3-ft shoulders. The directional hourly traffic flow is 2000 vehicles with 3% SUTs and 3% TTs. The total ramp density for this freeway segment is 2.33 ramps per mile. If the peak-hour factor is 0.90, what is the level of service of this compound-grade freeway segment

Answer:
4.5kg/min
Explanation:
Given parameters
if we take
The mass flow rate of the second stream =
The mass flow rate of mixed exit stream =
Now from mass conservation
The temperature of the mixed exit stream given as
Therefore the mass flow rate of second stream will be 4.5 kg/min.
