with the decrease of area of flow with the increase of area of flow when area of flow is constant none of the above
Answer Discuss in Comment
area of flow surface resistance slope of the bed of channel all of the above
depth of flow half of depth of flow one-quarter depth of flow twice the depth of flow
width of the channel one-quarter width of channel half the width of channel twice the width of the channel
equal to the depth of flow half the depth of flow twice the depth of flow 1.5 times the depth of flow
0.75 times the dia. of circular channel 0.81 times thedia. of circular channel diameter of circular channel 0.95 times the dia. of circular channel
0.81 times the diameter of circular channel 0.625 times the diameter of circular channel 0.75 times the diameter of circular channel diameter of circular channel
