Why construction is present near the bulb

Water, with a density of rho = 1125 kg/m 3 rho=1125 kg/m3, flows in a horizontal pipe. In one segment of the pipe, the flow speed is v 1 = 6.53 m/s v1=6.53 m/s. In a second segment, the flow speed is v 2 = 1.17 m/s v2=1.17 m/s.

If you are standing on a weighing scale in an elevator what happens to your weight if the elevator accelerates up or accelerates down? Are you going to weigh less, weigh more or the same?
