Extracted text: 3. In the following system, the flow rate of Q= 400 It/s is transmitted from the A chamber to the B chamber. There is a valve in the pipe where the diameter is large and there is a local loss due to the valve. Using the valve formula (K) as 10 (see formulas), calculate the distance H between the water face elevations of the two chambers. Draw the relative energy and piezometer lines.
