A pipeline of 5 cm diameter is reduced abruptly to 2.5 cm diameter at a section to enable measurement of the water flowing through it. The loss of head at the contraction is 0.5 m. Given that, in metric units, 2g = 4.43 and g = 3.132, the mean velocity in the reduced section will be-A-0.5 m/secB-1.1075 m/secC-1.566 m/secD-4.43 m/sec-D-4.43 m/sec

Question

APTITUDE CRACK · Accepted Answer

D 4.43 m/sec Head loss due to contraction is; Head loss = (0.5 * V2 square)/2g.
