Air discharges steadily through a horizontal nozzle and impinges on a stationary vertical plate as shown in figure.
The inlet and outlet areas of the nozzle are $0.1\:m^{2}\:\text{and}\:0.02\:m^{2}$ , respectively. Take air density as constant and equal to $1.2\:kg/\:m^{3}$. If the inlet gauge pressure of air is $0.36\:kPa$, the gauge pressure at point $O$ on the plate is __________ $kPa$ (round off to two decimal places).
