Air enters a turbine operating at steady state at 8 bar, 1400 k and expands to 0.8 bar. the turbine is well insulated, and kinetic and potential energy effects can be neglected. assuming ideal gas behavior for the air, what is the maximum theoretical work that could be developed by the turbine in kj per kg of air flow?

explanation:

probably not if net force is zero

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
