2 Laws for Thermodynamics Zeroth Law: A Ù C and B Ù C => A Ù B First Law – Closed System – Control Volume Sign conventions! Q>0: Heat into W>0: Work done by Second Law Closed System Control Volume Mass Conservation Closed System Control Volume Force Balance (Newton’s Second Law) – F=m a – For a stationary object Control volume transient analysis Mass balance Energy balance ignore kinetic potential energy effects assume states at inlet and exits are constant with time Entropy balance assume states at inlet and exits are constant with time
