Question

A mixture of ideal gases has a specific heat ratio of *k* = 1.35 and an apparent molecular weight of *M* = 44 kg/kmol. Determine the work, in kJ/kg, required to compress this mixture isentropically in a closed system from 100 kPa and 35°C to 700 kPa. The universal gas constant is *R _{u}* = 8.314 kJ/kmol·K.

The work required to compress this mixture is _______kJ/kg.

Step 1

Given information: Closed isentropic process

Step 2

Now, gas constant is the ratio of universal gas constant and equivalent molecular mass.

Step 3

For isentropic ...
