1. A gas with R= 0.277KJ/kgm*K and k = 1.384,
determine the following:
a.Values of cp and cv.
b.lf the gas would occupy 0.425m^3 volume at
517.11kPa and 26.7C, find its mass in kgm.
c.From conditions 2, if 31.65kJ are transferred
to the gas, what will be the resulting
temperature in C and pressure in kPa?
2. A closed vessel contains air at a
pressure of 140kPag and a temperature of 20C. Find the final gauge pressure in
psi if the air is heated at a constant volume to 100F. The atmospheric
pressure is 28inHg.
