Water is flowing through a vertical pipe having diameters of 150 mm and 100 mm at the bottom and upper ends, respectively. Calculate the kinetic head of water at the upper end if the flow velocity at the upper end is 0.5 m/s. Consider the acceleration due to gravity to be 10 m/s2.

What will be the value of Chezy's constant 'C' if the velocity of flow 'V' is 1.506 m/s, bed slope is 1 in 2000 and hydraulic mean depth 'm' is 1.5 m?

Water is flowing through a rectangular channel. The width and depth of the channel are 830 cm and 140 cm, respectively. If the discharge through the channel is 600 cusecs, then the specific energy of flowing water and the value of minimum specific energy are ______ and ______, respectively.
