Explanation / Answer

1) 16.3 - 10.8 = V x 1000 x 9.8 => V = 0.000561224 m3

2) Av = constant

0.02 x 0.02 x v = 0.095 x 0.095 x 2.8 => v = 63.175 m/s

water per hour = 3Av x density = 3 x 3.14 x 0.02 x 0.02 x 63.175 x 1000 = 238.16 kg

3) use the relation

P2 - P1 = 0.5 x density x (v12 - v22)

and A1v1 = A2v2 to get v1 and v2
