1. One kg of air is heated and compressed in a piston/cylinder system from 400 K, 100 kPa to 1200 K, 500 kPa. Find As (kJ/kg-K) via: (a) Thermofluids (b) Using the following ideal gas equation: Where: Here, T-K and Cp=kJ/kg-k a 0.9703 Cp = [²7/1 dr - Rin (13) dT T As = Cp = a +bT + cT² + dT³ b 6.790E-5 C 1.658E-7 d -6.786E-11

You run a race starting from rest and accelerating at 0.35 m/s2 until you cross the finish line in 14.0 seconds.  a) what is your final speed?

Help with the questions: 1- Continuity tells us that whatever the volume of fluid in a pipe passing a particular point per second, the same volume must pass every other point in a second. The fluid is not accumulating or vanishing along the way. A) True B) False 2- When a fluid moves from a wider area of a pipe to a narrower one, its speed increases. A) True B) False 3- A fluid exerts a net upward force on any object it surrounds, called the buoyant force. A) True B) False
