A"scale" is constructed with a 4--long cord and the20 block d. the cord is fixed to apin at
a and passes over two small pulleys at band
c.
determine the weight of the suspended blockat
b if the system is in equilibrium.
express your answer with
theappropriate units.
shouldn't tbc be equal to wd because they are on the
samepulley?

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.

What precautions should you take to prevent injuries when dealing with heavy loads?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false
