3. Consider a pumping device with a pressure of 10 kPa for the suction surface and an absolute pressure of 120 kPa for the transmission surface. The
diameters of the suction pipe and the transmission pipe are 110 and 100 mm, respectively, and the transmission flow rate is 1.2m$^3$/min. The lengths of
the suction pipe and the transmission pipe are 30m and 50m, respectively, the loss coefficient of the pipe friction is 0.008, the loss coefficient at the
inlet of the suction pipe is 0.4, the loss coefficient at the outlet of the transmission pipe is 1.1, and the loss coefficient of the transmission valve is 1.5.
When the axial power to drive this pump is 10 kW and the efficiency of the pump is 90%, calculate the following.
(1) Friction loss head of suction pipe (2) secondary loss of suction pipe head (3) Friction loss head of the transmission pipe
(4)Secondary loss head of the transmission pipe
(5) Jeonyangjeong (Korean traditional multicolored paintwork) (6) Vertical distance that this pump can pump
(7) Pressure difference between vacuum and pressure gauge (kPa)
(8)Instrument pressure at the pump outlet (kPa) when the vertical distance from the center of the pump to the transmission surface is 33m
