1.)100 g of water are mixed with 150 g of alcohol (w= 790kg/m3 ). What is the specific gravity of the resulting mixtures, assuming the fluids mixed completely?
2.)A certain location has barometric reading of 720 mm Hg and the gravitational acceleration is 9.2 m/s2 . If the temperature of mercury is 9 degree Celsius at which density is 12,850 kg/m3, compute the atmospheric pressure.
3.)In a certain steam plant, the turbine develops 1000 KW. The heat supplied to the steam in the boiler is 2800 KJ/kg, the heat rejected by the system to the cooling water in the condenser is 2100 KJ/kg and the feed pump work is 5KW. Calculate steam flow in kg/sec.
