A fluid with specific gravity 0.85 is flowing through a diameter 250 mm and 150 mm at the bottom and upper ends respectively. Determine the difference in datum head if the rate of flow through pipe is 0.04 m3/s. Take pressure at top and bottom as 27 N/cm2 and 10 N/cm2.
Water is flowing through a pipe of 3.8 cm diameter under a pressure of 20 N/cm2 (gauge) and with mean velocity of 3.7 m/s. Find the total head or total energy per unit weight of the water at a cross section, which is 7 m above the datum line.
