Aship has a displacement of 9600 tonnes with km 8.5m and kg 7.5m. a double bottom tank of length 18, width 14m has a centre line bulkhead. the starboard side of the tank is now filled to a depth of 0.6m with oil of relative density 0.95. calculate the resulting list angle.

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?
