Answer
a) Above the atmospheric pressure
b) $P=106kPa$
Work Step by Step
a) Judging from the figure you can assume that the pressur in the duct is above the atmospheric pressure, because the fluid column on the right is at higher level than the left side.
b) $P=P_{atm}+\rho*g*h=100000Pa+(13600\frac{kg}{m^3})*(9.81\frac{m}{s^2})*(0.045m)$
$P=106kPa$
