Question

Prob em 1 pts in Lab 03 water friction, for the dark blue circuit the head loss h h1-h2 across bend "C" at 30% and 40% flow are recorded in the table 3 I below. The actual flow rates, Reynolds number, Blasius friction factor, and required water and pipe properties are included in the table. From the given information, complete cells L16, M10, M12, M16, NI0, N12,NI6,010, 012 and O16 in table 3.1 and determine the average minor loss coefficient K, for this bend. 0 3 Table 3.1 Loss Coefficients Kb of Bend C(Standard 90) Blasius FrictionBend C-Standard 90 R/D 1 Flow Rate Velocity No. 4Rotameter Bend Coet.
