Avessel displacing 2 tons has a km=6,5 m. a weight of 25 tons shifted 20 m transversely across the deck causes a plumb line length 10 m to be deflected by 0.1 m. kg of the inclining weight 10.5 m. if there remains to be installed a generator weighting 100 tons at kg= 3 m, determine the lightship displacement and kg of the ship.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
