The internal energy of helium at 300 K as well as 1atm is 3800 KJ, and the molar volume at the same temp. is 24.63 L/mol. Compute the enthalpy of helium at this temperature and pressure as well as the rate at which enthalpy is transported by a strem of helium at 300 K and 1atm whose molecular flow rate is 250Kmol/hr. R=0.082 L(atm)/mol K, R=8.314 J/Kmol. Compute the maximum work of the system
