Refngerant-134a is used as the working fluid in a simple ideal rankine cycle which operates the boiler at 1400 kpa and the condenser at 10 °c the mixture at the exit of the turbine has a quality of 98 percent determine a) the turbine inlet temperature, b) the cycle thermal efficiency, and c) the back-work ratio of this cycle

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.
