For a channel with subcritical flow condition, a bridge opening constriction produces a reduction of about 10% of the original channel width due to the structural elements. Therefore, hydraulically speaking, the water is accelerated at the opening and its water depth is lower than the water depth from the upstream bridge. True or False? Explain.

Expert Solution

So, it is true that the water depth at downstream is less than the water depth at upstream when the flow is in subcritical condition and the width of channel is decreased.

In a uniform open channel flow: The total energy remains constant along the channel The total energy line either rises or falls along the channel depending on the state of the flow The specific energy decreases along the channel The line representing the total energy is parallel to the bed of the channel In which of the following situations, the flow is uniform? Flow in channel contraction or expansion Flow in the vicinity of a bridge pier Flow at the...

Patch-Clamp instruments allow researchers to measure the opening and closing of a single channel in a membrane. A typical acetylcholine receptor channel passes about 5 pA (picoamperers) of ionic current over a period of 5 msec at -60mV. Given that an electric current of 1 A is about 6.2x10^18 electrical charges per second, how many ions (potassium or sodium) pass through the channel during the time that it is open?
