In figure below, water at 10°C is flowing from section 1 to section 2. At section 1, which is 25 mm in diameter, the gage pressure is 345 kPa and the velocity of flow is 3.0 m/s. Section 2, which is 50 mm in diameter, is 2.0 m above section 1. Assuming there are no energy losses in the system, calculate the pressure P2 Total head ti/2g = Velocity head %3D P1/Y = Pressure head 22 Flow 3, = Elevation head Reference level Use this equation P,ly + Z, + V,212g = P y + Z, + V,/2g 2.
The open tank has a four (4) liquids inside. The absolute pressure at the bottom is 250 kPa and the specific gravity of three (3) liquids oil, water, and mercury is 0.88, 1, and 13.6 respectively. The olive is one (1) of them, determine its specific gravity if the height of four (4) liquids oil, water, olive and mercury is 1.45 m, 2.45 m, 2.8 m, and 0.39 m respectively. And draw the open tank with a consecutive layer of four (4) liquids. Notes: 1. atmospheric pressure is 101.03 kPa 2. Since the tank is open, the atmospheric pressure is included.
