Water contained in a piston-cylinder assembly as shown in the Figure below, initially at 1.5 ??? and a quality of 20%, is heated at a constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. Show the processes of the water in series on a sketch of the ?-? diagram. For the overall process of the water, evaluate the work and heat transfer, each in ??⁄??. Kinetic and potential effects are negligible. (please show your work)

A compacted asphalt concrete specimen contains 4.8% asphalt binder by weight of total mix and aggregate blend with blended specific gravity of 2.689. The average bulk density of the compacted specimen is 2.414 g/cm3 . Ignoring absorption of aggregate particles, 1) compute the VTM, VMA, VFA, and D/B of the specimen. 2) Draw the phase diagram of this asphalt mixture.
- Asphalt binder specific gravity, Gb: 1.03
- Passing #200 fine fillers (%): 4.7 %

Part 1: A five-sided closed field traverse has the following distances in feet: AB = 647.25; BC = 203.03; CD = 720.35; and DE = 610.24; and EA = 285.13. The interior angles are as follows (measured as angles to the right): A = 100º 45' 37"; B = 231º 23' 43"; C = 17º 12' 59"; D = 89º 03' 28"; and E = 101º 34' 24". The bearing of AB is S 53º 04' 43" E. Determine the bearings of each side

minimize the energy loss of liquid moving in a pipeline. You as a
civil engineer check that they are correct or not. Suggestion 1 –
Increase the diameter of the pipe
Suggestion 2 – Increase the number of bends of the pipe
Suggestion 3 – Reduce the length of the pipe
Suggestion 4 – Increase the velocity of the liquid of the
pipe
Suggestion 5 – Allow the corrosion inside the pipe
Suggestion 6 – fully open the valves of the pipe
