1.The pressure in the steam condenser of a nuclear power plant is 1 psia. Calculate the absolute pressure head, the gage pressure, the gage pressure head, the vacuum pressure, and the vacuum pressure head under standard conditions.
2.A barometer reads 29.41 inches of mercury neglecting surface tension and vapor pressure find the atmospheric pressure in lbf/in^2
3.If theta = 60 degrees and F=450N, determine the magnitude of the resultant force and its direction, measured counterclockwise from the positive axis. The other force is F=700N with a 15 degree angle to the x-axis .
