a) In a vertical pipe carrying water, see Figure 3, pressure gauges are inserted at points A and B where the pipe diameters are 0.15 m and 0.075 m respectively. The point B is 2.5 m below A and when the flow rate down the pipe is 0.02 m/s, the pressure at B is 14715N/m greater than that at A. Assuming the losses in the pipe between A and B can be expressed as: k where vis the velocity at A. 2g 1. Find the value of the value of k 2. If the gauges at A and B are replaced by tubes filled with water and connected to a U-tube containing mercury of relative density 13.6, give a sketch showing how the levels in the two limbs of the U-tube differ and calculate the value of this difference in metres. da = 0.2m OA dg = 0.2m OB Figure 3: Te be used for Oue 4a
