Classify the following flow cases as steady, unsteady, uniform, or non-uniform: Flow in a pipe leading from an infinite reservoir, while the valve between the pipe and reservoir is: being opened or closed: fixed open Flow in a pipe leading from a finite reservoir, while the valve between the pipe and reservoir is: being opened or closed fixed open Flow or a river around bridge piers: standing on the bridge in a boat drifting with the current Movement of a flood down a valley after the collapse of a dam: standing on the bank at the dam site running downstream on the bank, keeping pace with a surge that forms at the front of the flood wave flow in a channel contraction or expansion flow at a channel entrance flow in the vicinity of a bridge pier flow at the end of a long prismatic channel
