The liquid level at the bottom of the tower is 4 meters above the ground, the pump inlet is 0.5 meters above the ground, and the density of the liquid at that level in the tower is 0.9. Determine the static pressure at the pump inlet. P=ρgh=0.9*1000*9.81*（4-0.5）= 30.9 kpa Is this correct? . .
1000×0.9×9.81×(4 - 0.5) = 30901.5Pa = 30.9 kPa
P_table = 30.9 kPa, p_abs = 313 kPa
900*9.81*（4-0.5）＝30901.5Pa
P=ρgh=0.9*1000*9.81*（4-0.5）= 30.9 kPa
P=ρgh=0.9*1000*9.81*（4-0.5）= 30.9 kPa
p=ρgh=1000×0.9×9.81×(4 - 0.5) = 30901.5Pa
