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.

Estimate the change in specific internal energy au and specific enthalpy h from inlet to outlet for ethylene glycol (a liquid) flowing through each of the following devices: (a) a heat exchanger where the glycol temperature increases from 20 °c to 80 °c; (b) a pump operating at about 25 °c and increasing the glycol pressure from 100 kpa to 8 mpa.
