2. If 0.17 kg/s of air are compressed isothermally from Pi = 96 kPaa and V, = 0.13 m/s to p2 = 620 kPaa, find the work, the change of entropy, and heat for: a) a nonflow process, and b) a steady flow process with V1 = 15 m/s and V2 = 60 %3D %3D m/s.

Q1 / A: Derive the steaay flow energy equation and reduce it for: a. A turbine ( Reversible Process) b. A pump ( Reversible Process) c. A nozzle ( Reversible Process) d. A throttling ( Irreversible Process) Assume that the working fluid is an ideal gas and the entrance and exit are at the same level. B- For a reversible adiabatic process prove the equation pvr = constant can apply for the relation between pressure and specific volume for a perfect gas. %3D

Thermodynamics: Please show me how to solve the given practice problems in step by step solution.

3. If 10 kg/min of air are compressed isothermally from p1 = 96 kpa and V1 = 7.65 m3/min to p2 = 620 kpa, find the work, the change of entropy, and the heat for (a) nonflow process and (b) a steady flow process with v1 = 15 m/s and v2 = 60 m/s.

Find the velocity (in ft/s) at a second point a short distance away, where the pressure is 83 psia, from the isentropic flow of nitrogen gas in a 2-in-ID pipe. At the first point, the velocity is 409 ft/sec, pressure is 85 psia, and unit weight is 0.655 lb/ft³

Isentropic efficiency of a turbine. If the process between the inlet state and the exit pressure.

B-Prove that the entropy is a property
