Please could you state which formulae you are using before applying it so I can see how the question is answered
Thanks

Transcribed Image Text: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.
