A canister filled with 3.5 mol of single-atom helium gas has a temperature of 300 K. What is the approximate total internal energy of the gas? (Recall that
3
the equation for kinetic energy due to translation in a gas is: nRT; the
2
equation for kinetic energy due to rotation of a molecule in a gas is: nRT; and
R = 8.31 J/(mol-K).)

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
