These are Multiple Choice Questions (MCQ) from Exams posted before May 2024. These MCQs get orphaned after the system upgrade.
The Venturi meter is used to measure the presence of flow in the pipe system, the section of the pipe with the smallest pressure is called:
A principle in flow measurement which states that the increase in kinetic energy per unit weight is equal to the decrease in the potential energy per unit weight is known as:
It is a pressure force that acts as the body submerged in a liquid at rest which is equal to the weight of the fluid displaced by the submerged body either partially or completely.
It is an overflow structure built across an open channel for the purpose of measuring and controlling the flow.
In an open channel flow, hydraulic jump occurs when:
The volume of fluid passing a certain section of the stream, pipe, or channel, which has the dimension in cubic meter per second is:
In an open channel flow, the discharge at a certain section can be measured by the use of the weir, given by the equation: $Q = \frac{8}{15}C \sqrt{2g} ~ \tan (\frac{1}{2}\theta) ~ H^{5/2}$
It is defined as a hydrograph with a volume of 1 inch of runoff resulting from a rainstorm of specified duration and a real pattern.
The volume of fluid passing a section of the stream per unit time is known as:
One of the rational methods of determining the reservoir-capacity yield analysis in dam design is known as:
A mass of liquid translated horizontally to the left with a uniform velocity will have its surface:
In pipe flow, the horsepower of the pump can be computed as the function of:
The vena contracta of a sharp-edged hydraulic orifice usually occurs:
In a system of parallel pipes, which of the following is true:
A series of siphon pipes of uniform diameter are to draw water to irrigate the farm instead of using the traditional method of flooding the area.
It is a term to denote the temperature which is the average of the monthly mean for the year.
In an open channel flow, the discharge at a certain section can be measured by the use of the equation: $Q = \frac{2}{3}C \sqrt{2g} ~ LH^{3/2} + \frac{8}{15}C \sqrt{2g} ~ \tan (\frac{1}{2}\theta) ~ H^{5/2}$
A system of streamline and orthogonal lines which show the idealized flow pattern for a given system of boundaries.
In pipe flow, applying the Bernoulli equation from one section (upstream side) to another section (downstream side) the total energy on one section (downstream side) is expressed as:
Water that flows from the atmosphere to the earth’s surface in any variety of forms is known as:
The stability of a floating body is determined by the relative position of the center of gravity of the floating body and its metacenter.
A dimensionless number or parameter in dynamic similarity expressed as the ratio of the inertia force to pressure forces is known as:
A mechanical device which when installed in the pipe will extract energy from the system.
It is the term to denote the temperature range between the highest and lowest temperature recorded for a particular day.
The weight of the body of fluid defined as the earth’s gravitational pull of the body is given by the equation:
It is the term used in the case of pipe flowing under pressure, it is the circumference of the circular section, while in the case of a rectangular open channel flow, it is the sum of the base and the two sides.
