A conical tube of length 2.0m is fixed vertically with its smaller end upwards as shown in Figure 2. The velocity of flow at the smaller end is 5m/s while at the lower end is 2 m/s. The pressure head at the smaller end is 2.5m of liquid. The loss of head in the tube is given by 2g0.35(v1v2)2, where v1 is the velocity of the smaller end and v2 at the lower end respectively. Determine the pressure head at the lower end. (Notes: Flow take place in downward direction) Figure 1
