one mole of an ideal gas at 1.0 mpa and 300k is heated at constant pressure till the volume is doubled and then it is
Dry air is contained in a tank wit fixed volume at 200oC and a pressure of 5 bar. Then the fluid is heated so that its temperature reaches up to 300oC. If the volume of the tank is 0.2 m3, find the transferred heat and final pressure and the change i..
A perfect gas (methane) undergoes a reversible polytropic process in which the polytrotic exponent is 1.4. 1) Using the first law, arrive at an expression for heat transfer per unit mass solely as a function of the temperature difference (change in T..
at steady state. a power cycle generates 100 mw of electricity while discharging energy by heat transfer at a rate of
Discuss the condition of the water still in the bag and the reason for that condition. Base your discussion on topics that have been covered in this course so far.
Air at 22 kPa, 220K and 250 m/s enters a turbojet engine in flight at an altitude of 10,000m. The diffusor slows the air down to a very low speed relative to its inlet. The pressure ratio across the compressor is 12. The turbine inlet temperature is ..
the surface pressure of venus is about 90 bar and the surface temperature is ap-proximately 880 degrees f. the
compute the design factor of a rod that is under a tensile load of 3125 lb. the rod is rectangular 1.5 in by 3.5 in and
We have 0.25 lb of refrigerant 134a at 35 psi, and a quality of x=0.15. If it is expanded, in a constant pressure process, to two times its original volume, determine the final temperature, and find the work of the constant process.
r-134a is loaded into a weighted pistoncylinder unit. the mass of refrigerant is 10 kg. before heating measurements
