complete solution and box final answer

Two pipes, P1 and P2 both have diameters of 3 cm. Another pipe P3 has a diameter of 4 cm. Alcohol of S.G. 0.8 enters P1 at 6 m/s while water enters P2 at 10 m/s. Assuming ideal mixing of incompressible fluids, compute the exit velocity and mass density of the mixture at P3. The temperature is 20℃.

Glycerin at 20 °C flows upward in a vertical 75-mm-diameter pipe with a centerline velocity of 3.8 m/s. Determine the (a) head loss and (b) pressure drop in a 10-m length of the pipe.

Water is pumped up from a reservoir to a smaller holding tank. If the flow rate through the pipe is 50 LPM, find the NPSH available immediately before the pump. The length of the pipe from the reservoir to the pump is 13.1 meters, and its diameter is 2.8 cm. The distance is h2=6.8 m.  Assume a friction factor of 0.021. The vapor pressure of water at the current temperature is 2,399 Pa.  Current atmospheric pressure is 95,194 Pa.  The density of water is 991 kg/m^3

The liquid in the figure has a specific gravity of 3.0. The gage pressure Pa=70Kpa and Pb is atmospheric. The orifice is 75mm⌀ and C=CV=0.95 with h=1.5m, determine the discharge and the head loss in the orifice.
