A thin orifice plate inside a pipe causes a large drop in pressure between location 1 and location 2 equal to 145 kPa. Water flows at 500 gpm (gallons per minute). The diameter of the pipe is 10 cm and the diameter of the orifice in the plate is 6 cm. Use the control volume between location 1 and location 2. Compute the magnitude of the force on the orifice plate. Assume a constant density of 1000 kg/m3.

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?

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
