A 50 mm diameter siphon discharges oil (SG=0.88) from a reservoir (elev. 20m) into open air (elev. 15m). The head loss from the reservoir (point 1) to the summit (point 2, elev. 22m) is 2.5 times the velocity head in the siphon and head loss from the summit to the discharge end is 4 times the velocity head in the siphon. What is the absolute pressure at the summit (point 2) assuming the atmospheric pressure to be 101.3 kPa?
