Spring 2006 1 ME 201 Thermodynamics Homework #4 Due Monday, January 30, 2006 1. Assuming an ideal gas calculate the specific volume in the appropriate units for: a. N 2 at 500 kPa and 900 K b. Neon at 1 psia and 500 R c. Air at 14.7 psia and 72 ° F 2. Calculate the specific internal energy change for H 2 by assuming a temperature variation in c v (i.e., integrating) at 700 kPa as its temperature changes from 350 K to 1300 K. 3. Calculate the specific enthalpy change (in the appropriate units) for the following

Unformatted text preview: ideal gas processes by first using an average c P and then by using the ideal gas tables. a. CO 2 at 2000 kPa goes from 500 K to 1300 K b. CO 2 at 2000 kPa goes from 500 K to 600 K c. Air at 40 psia and 270F goes to 11 psia and 270F 4. Carefully draw the following graph using air as an ideal gas. a. temperature versus pressure showing lines of constant specific volume and specific enthalpy...
