Alow-speed cessna 150 flying at 5,000 ft pressure altitude has an indicated airspeed of 250 ft/s. if the outside temperature is 30°f and there is a 50-ft/s headwind, what is the aircraft's ground speed? (the airspeed indicator of the plane indicates the equivalent airspeed, not the true airspeed.)

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i.e., a violation of one statement leads to the violatio the other statement)

Aheavily insulated piston-cylinder device contains 0.02 m3 of steam at 300 kpa and 200 °c. 1.2 mpa. d this process. team is now compressed in a reversible manner to a pressure of etermine the entropy change and the work done on the steam during this process
