Figure 3.1 shows a water tank with a pressure meter and a valve. When the valve is closed, the reading from the pressure meter is 21 kN/m². The valve is then opened, and the water flows out until the reading from pressure meter shows the value of 5.5 kN/m². Assume that the water head loss is negligible, then (a) calculate the water height level, h, measured from the valve outlet; (b) if the outlet diameter is 50 mm, calculate the flow rate when the valve is open and the reading from the pressure meter is 5.5 kN/m²; (c) if we seal the top of water tank with a lid (air tight), describe what happens when we open the water valve? State your assumptions.
