A four‐lane freeway (two lanes in each direction) operates at flow rate of 1700 during the peak hour. It has 11‐ft lanes, 4‐ft shoulders, and there are three ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The freeway has only regular users. There are 8% heavy trucks, and it is on rolling terrain with a peak‐hour factor of 0.85. It is known that 12% of the AADT occurs in the peak hour and that the directional factor is 0.6.
What is the freeway’s AADT?

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
