Chapter 6, Problem 6.15P

Provide complete solution and detailed diagram.  A gas has an enthalpy of 2400 KJ/kg and internal energy of 2200 KJ/kg. Find the specificvolume of the gas at 950 Kpa pressure. A. 0.12 m3/kg     B. 0.93 m3/kg    C. 0.72 m3/kg            D. 0.21 m3/kg

Q1: a) If for a given gas (Ou/ov)0, find u, the specific internal energy if c, is constant. b) If the equation of state for the gas in part (a) is given by v-(RT/p) = a, find c,- c, for that gas. c) Show that (@h/op)r=-C, (@T/ôp)n.

Identify the Enthalpy of State 1 to 4 (h1, h2, h3 and h4)

A piston cylinder device with stops as shown contains water initially at 25 oC and 100 kPa “State 1”. Heat is then added, and piston moves till it hits the stops where cylinder contains two phase mixture with quality x2 = 0.616 “State 2”. Heating continues until final Pressure is 300 kPa “State 3”. 1) What is the final specific volume (m3/kg)? 1.2217 Not listed 1.1202 1.0440 0.9864 1.0551 2) What is the boundary work (kJ/kg)? 122.07 98.54 Not listed 104.30 116.85 111.92 3) What is the final Temperature (oC)? 457.1 371.1 441.6 408.0 Not listed 522.6

Argon (molar mass 40 kg/kmol) compresses reversibly in an adiabatic system from 5 bar, 25 °C to a volume of 0.2 m If the initial volume occupied was 0.9 m calculate the final pressure in bar to 2 decimal places.. Assume nitrogen to be a perfect gas and take cv 0.3122kJ/kgK. Question 12 of 84 A Moving to another questlon will save this response.

ONLY B,C,D ( NEED NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE).
