Question

Air discharges steadily through a horizontal nozzle and impinges on a stationary vertical plate as shown in figure.
Air jet from a nozzle hitting a vertical plate
The inlet and outlet areas of the nozzle are 0.1 m20.1\text{ m}^2 and 0.02 m20.02\text{ m}^2, respectively. Take air density as constant and equal to 1.2 kg/m31.2\text{ kg/m}^3. If the inlet gauge pressure of air is 0.36 kPa0.36\text{ kPa}, the gauge pressure at point O on the plate is ______ kPa (round off to two decimal places).
