Wаter flоws upwаrd in а 6 cm-diameter pipe at a velоcity оf 4 m/s. The pipe length between points (1) and (2) is 5 m, and point (2) is 3 m higher than point (1). A mercury manometer connected between points (1) and (2) shows a reading of: h=225 mmwith pressure at point (1) higher than at point (2). Given: γHg=133,100 N/m3,γw=9,790 N/m3 Determine the head loss hf in meters. hint: use Bernoulli equation to calculate pressure drop then calculate the head losses.
