पानी की आठ एक समान बूंदें वायु में 5 सेमी/सेकंड के स्थिर सीमांत वेग (terminal velocity) से गिर रही हैं। यदि ये बूंदें मिलकर एक बड़ी बूंद बनाती हैं, तो नया सीमांत वेग क्या होगा?

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.
