A 50 mm. diameter siphon is drawing oil (sp.gr. = 0.82) from an oil reservoir as shown on the figure. The head loss frompoint 1 to point 2 is 1.50 m and from point 2 to point 3 is 2.40 m. Unit weight of water is 9.79 Kn/m3.a. If the total length of the 50 mm diam. Siphon is 8 m., calculate the friction factor f.b. Calculate the discharge of oil from the siphon.c. Calculate the lowest vacuum pressure of the siphon (Vacuum pressure is much lower, even lower thanatmospheric pressure. Vacuum pressure exists in the siphon thus the pressure difference between vacuum andatmospheric allows for flow to take place through the siphon. The lowest vacuum pressure creates a greaterpressure difference, and so allows maximum flow through the siphon).50 mm øsiphon2mOil (s.g.-0.82)5m
