Apipeline 1200ft long and 8in. in diameter hasat its inlet point
75ft of available hydraulic energy with respectto the reference
level. the velocity in the pipe is 5fps; thepressure at its end is
12psi. the elevation at the end of the pipeis 10ft above reference
level. how much energy in horsepower islost by the water while
flowing through the pipe?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
